The WP Child Theme Generator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wctg_easy_child_theme() function in all versions up to, and including, 1.1.1. This makes it possible for unauthenticated attackers to create a blank child theme and activate it cause the site to whitescreen.

The WP Blog Post Layouts plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.1.3. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary PHP files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

The The Plus Addons for Elementor Page Builder plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘forgoturl’ attribute within the plugin's WP Login & Register widget in all versions up to, and including, 5.5.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

In the Linux kernel, the following vulnerability has been resolved: enic: Validate length of nl attributes in enic_set_vf_port enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE is of length PORT_PROFILE_MAX and that the nl attributes IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX. These attributes are validated (in the function do_setlink in rtnetlink.c) using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation using the policy is for the max size of the attributes and not on exact size so the length of these attributes might be less than the sizes that enic_set_vf_port expects. This might cause an out of bands read access in the memcpys of the data of these attributes in enic_set_vf_port.

In the Linux kernel, the following vulnerability has been resolved: soundwire: cadence: fix invalid PDI offset For some reason, we add an offset to the PDI, presumably to skip the PDI0 and PDI1 which are reserved for BPT. This code is however completely wrong and leads to an out-of-bounds access. We were just lucky so far since we used only a couple of PDIs and remained within the PDI array bounds. A Fixes: tag is not provided since there are no known platforms where the out-of-bounds would be accessed, and the initial code had problems as well. A follow-up patch completely removes this useless offset.

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: u_audio: Fix race condition use of controls after free during gadget unbind. Hang on to the control IDs instead of pointers since those are correctly handled with locks.

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Use variable length array instead of fixed size Should fix smatch warning: ntfs_set_label() error: __builtin_memcpy() 'uni->name' too small (20 vs 256)

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/cs_dsp_ctl: Use private_free for control cleanup Use the control private_free callback to free the associated data block. This ensures that the memory won't leak, whatever way the control gets destroyed. The original implementation didn't actually remove the ALSA controls in hda_cs_dsp_control_remove(). It only freed the internal tracking structure. This meant it was possible to remove/unload the amp driver while leaving its ALSA controls still present in the soundcard. Obviously attempting to access them could cause segfaults or at least dereferencing stale pointers.

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: Fix uninit-value in nci_rx_work syzbot reported the following uninit-value access issue [1] nci_rx_work() parses received packet from ndev->rx_q. It should be validated header size, payload size and total packet size before processing the packet. If an invalid packet is detected, it should be silently discarded.

In the Linux kernel, the following vulnerability has been resolved: efi: libstub: only free priv.runtime_map when allocated priv.runtime_map is only allocated when efi_novamap is not set. Otherwise, it is an uninitialized value. In the error path, it is freed unconditionally. Avoid passing an uninitialized value to free_pool. Free priv.runtime_map only when it was allocated. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.

In the module RSI PDF/HTML catalog evolution (prestapdf) <= 7.0.0 from RSI for PrestaShop, a guest can perform SQL injection via `PrestaPDFProductListModuleFrontController::queryDb().'

In Kostal PIKO 1.5-1 MP plus HMI OEM p 1.0.1, the web application for the Solar Panel is vulnerable to a Stored Cross-Site Scripting (XSS) attack on /file.bootloader.upload.html. The application fails to sanitize the parameter filename, in a POST request to /file.bootloader.upload.html for a system update, thus allowing one to inject HTML and/or JavaScript on the page that will then be processed and stored by the application. Any subsequent requests to pages that retrieve the malicious content will automatically exploit the vulnerability on the victim's browser. This also happens because the tag is loaded in the function innerHTML in the page HTML.

ClassGraph before 4.8.112 was not resistant to XML eXternal Entity (XXE) attacks.

Actual Analyzer through 2014-08-29 allows code execution via shell metacharacters because untrusted input is used for part of the input data passed to an eval operation.

Multiple directory traversal vulnerabilities in the TFTP Server in Distinct Intranet Servers 3.10 and earlier allow remote attackers to read or write arbitrary files via a .. (dot dot) in the (1) get or (2) put commands.

In the Linux kernel, the following vulnerability has been resolved: dma-buf/sw-sync: don't enable IRQ from sync_print_obj() Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from known context") by error replaced spin_unlock_irqrestore() with spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite sync_print_obj() is called from sync_debugfs_show(), lockdep complains inconsistent lock state warning. Use plain spin_{lock,unlock}() for sync_print_obj(), for sync_debugfs_show() is already using spin_{lock,unlock}_irq().

In the Linux kernel, the following vulnerability has been resolved: bpf: Allow delete from sockmap/sockhash only if update is allowed We have seen an influx of syzkaller reports where a BPF program attached to a tracepoint triggers a locking rule violation by performing a map_delete on a sockmap/sockhash. We don't intend to support this artificial use scenario. Extend the existing verifier allowed-program-type check for updating sockmap/sockhash to also cover deleting from a map. From now on only BPF programs which were previously allowed to update sockmap/sockhash can delete from these map types.

In the Linux kernel, the following vulnerability has been resolved: tls: fix missing memory barrier in tls_init In tls_init(), a write memory barrier is missing, and store-store reordering may cause NULL dereference in tls_{setsockopt,getsockopt}. CPU0 CPU1 ----- ----- // In tls_init() // In tls_ctx_create() ctx = kzalloc() ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1) // In update_sk_prot() WRITE_ONCE(sk->sk_prot, tls_prots) -(2) // In sock_common_setsockopt() READ_ONCE(sk->sk_prot)->setsockopt() // In tls_{setsockopt,getsockopt}() ctx->sk_proto->setsockopt() -(3) In the above scenario, when (1) and (2) are reordered, (3) can observe the NULL value of ctx->sk_proto, causing NULL dereference. To fix it, we rely on rcu_assign_pointer() which implies the release barrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is initialized, we can ensure that ctx->sk_proto are visible when changing sk->sk_prot.

In the Linux kernel, the following vulnerability has been resolved: netfilter: tproxy: bail out if IP has been disabled on the device syzbot reports: general protection fault, probably for non-canonical address 0xdffffc0000000003: 0000 [#1] PREEMPT SMP KASAN PTI KASAN: null-ptr-deref in range [0x0000000000000018-0x000000000000001f] [..] RIP: 0010:nf_tproxy_laddr4+0xb7/0x340 net/ipv4/netfilter/nf_tproxy_ipv4.c:62 Call Trace: nft_tproxy_eval_v4 net/netfilter/nft_tproxy.c:56 [inline] nft_tproxy_eval+0xa9a/0x1a00 net/netfilter/nft_tproxy.c:168 __in_dev_get_rcu() can return NULL, so check for this.

In the Linux kernel, the following vulnerability has been resolved: Input: cyapa - add missing input core locking to suspend/resume functions Grab input->mutex during suspend/resume functions like it is done in other input drivers.

In the Linux kernel, the following vulnerability has been resolved: stm class: Fix a double free in stm_register_device() The put_device(&stm->dev) call will trigger stm_device_release() which frees "stm" so the vfree(stm) on the next line is a double free.

In the Linux kernel, the following vulnerability has been resolved: media: stk1160: fix bounds checking in stk1160_copy_video() The subtract in this condition is reversed. The ->length is the length of the buffer. The ->bytesused is how many bytes we have copied thus far. When the condition is reversed that means the result of the subtraction is always negative but since it's unsigned then the result is a very high positive value. That means the overflow check is never true. Additionally, the ->bytesused doesn't actually work for this purpose because we're not writing to "buf->mem + buf->bytesused". Instead, the math to calculate the destination where we are writing is a bit involved. You calculate the number of full lines already written, multiply by two, skip a line if necessary so that we start on an odd numbered line, and add the offset into the line. To fix this buffer overflow, just take the actual destination where we are writing, if the offset is already out of bounds print an error and return. Otherwise, write up to buf->length bytes.

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix loop termination condition in gss_free_in_token_pages() The in_token->pages[] array is not NULL terminated. This results in the following KASAN splat: KASAN: maybe wild-memory-access in range [0x04a2013400000008-0x04a201340000000f]

Cross Site Scripting vulnerability in Tessi Docubase Document Management product 5.x allows a remote attacker to execute arbitrary code via the idactivity parameter.

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails Calling a6xx_destroy() before adreno_gpu_init() leads to a null pointer dereference on: msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL); as gpu->pdev is only assigned in: a6xx_gpu_init() |_ adreno_gpu_init |_ msm_gpu_init() Instead of relying on handwavy null checks down the cleanup chain, explicitly de-allocate the LLC data and free a6xx_gpu instead. Patchwork: https://patchwork.freedesktop.org/patch/588919/

In the Linux kernel, the following vulnerability has been resolved: iio: adc: PAC1934: fix accessing out of bounds array index Fix accessing out of bounds array index for average current and voltage measurements. The device itself has only 4 channels, but in sysfs there are "fake" channels for the average voltages and currents too.

An issue was discovered in the friendlycaptcha_official (aka Integration of Friendly Captcha) extension before 0.1.4 for TYPO3. The extension fails to check the requirement of the captcha field in submitted form data, allowing a remote user to bypass the captcha check. This only affects the captcha integration for the ext:form extension.

In the Linux kernel, the following vulnerability has been resolved: tpm_tis_spi: Account for SPI header when allocating TPM SPI xfer buffer The TPM SPI transfer mechanism uses MAX_SPI_FRAMESIZE for computing the maximum transfer length and the size of the transfer buffer. As such, it does not account for the 4 bytes of header that prepends the SPI data frame. This can result in out-of-bounds accesses and was confirmed with KASAN. Introduce SPI_HDRSIZE to account for the header and use to allocate the transfer buffer.

In the Linux kernel, the following vulnerability has been resolved: tracing/probes: fix error check in parse_btf_field() btf_find_struct_member() might return NULL or an error via the ERR_PTR() macro. However, its caller in parse_btf_field() only checks for the NULL condition. Fix this by using IS_ERR() and returning the error up the stack.

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: Add callback function pointer check before its call In dpu_core_irq_callback_handler() callback function pointer is compared to NULL, but then callback function is unconditionally called by this pointer. Fix this bug by adding conditional return. Found by Linux Verification Center (linuxtesting.org) with SVACE. Patchwork: https://patchwork.freedesktop.org/patch/588237/

In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: extend minimum interval restriction to entire cycle too It is possible for syzbot to side-step the restriction imposed by the blamed commit in the Fixes: tag, because the taprio UAPI permits a cycle-time different from (and potentially shorter than) the sum of entry intervals. We need one more restriction, which is that the cycle time itself must be larger than N * ETH_ZLEN bit times, where N is the number of schedule entries. This restriction needs to apply regardless of whether the cycle time came from the user or was the implicit, auto-calculated value, so we move the existing "cycle == 0" check outside the "if "(!new->cycle_time)" branch. This way covers both conditions and scenarios. Add a selftest which illustrates the issue triggered by syzbot.

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Avoid unnecessary destruction of file_ida file_ida is allocated during cdev open and is freed accordingly during cdev release. This sequence is guaranteed by driver file operations. Therefore, there is no need to destroy an already empty file_ida when the WQ cdev is removed. Worse, ida_free() in cdev release may happen after destruction of file_ida per WQ cdev. This can lead to accessing an id in file_ida after it has been destroyed, resulting in a kernel panic. Remove ida_destroy(&file_ida) to address these issues.

In the Linux kernel, the following vulnerability has been resolved: fuse: clear FR_SENT when re-adding requests into pending list The following warning was reported by lee bruce: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 8264 at fs/fuse/dev.c:300 fuse_request_end+0x685/0x7e0 fs/fuse/dev.c:300 Modules linked in: CPU: 0 PID: 8264 Comm: ab2 Not tainted 6.9.0-rc7 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) RIP: 0010:fuse_request_end+0x685/0x7e0 fs/fuse/dev.c:300 ......

During the read, bit FR_SENT will be set on the request. (2) calls fuse_dev_write() to send an USE_NOTIFY_RESEND notify The resend notify will resend all processing requests, so the INIT request is moved from processing list to pending list again. (3) calls fuse_dev_read() with an invalid output address fuse_dev_read() will try to copy the same INIT request to the output address, but it will fail due to the invalid address, so the INIT request is ended and triggers the warning in fuse_request_end(). Fix it by clearing FR_SENT when re-adding requests into pending list.

Quoted from reply of Shinichiro Kawasaki: "I confirmed that the trigger commit is dbf8e63f48af as Yi reported. I took a look in the commit, but it looks fine to me. So I thought the cause is not in the commit diff. I found the WARN is printed when the f2fs is set up with multiple devices, and read requests are mapped to the very first block of the second device in the direct read path. In this case, f2fs_map_blocks() and f2fs_map_blocks_cached() modify map->m_pblk as the physical block address from each block device. It becomes zero when it is mapped to the first block of the device. However, f2fs_iomap_begin() assumes that map->m_pblk is the physical block address of the whole f2fs, across the all block devices. It compares map->m_pblk against NULL_ADDR == 0, then go into the unexpected branch and sets the invalid iomap->length. The WARN catches the invalid iomap->length. This WARN is printed even for non-zoned block devices, by following steps. - Create two (non-zoned) null_blk devices memory backed with 128MB size each: nullb0 and nullb1. # mkfs.f2fs /dev/nullb0 -c /dev/nullb1 # mount -t f2fs /dev/nullb0 "${mount_dir}" # dd if=/dev/zero of="${mount_dir}/test.dat" bs=1M count=192 # dd if="${mount_dir}/test.dat" of=/dev/null bs=1M count=192 iflag=direct ..." So, the root cause of this issue is: when multi-devices feature is on, f2fs_map_blocks() may return zero blkaddr in non-primary device, which is a verified valid block address, however, f2fs_iomap_begin() treats it as an invalid block address, and then it triggers the warning in iomap framework code. Finally, as discussed, we decide to use a more simple and direct way that checking (map.m_flags & F2FS_MAP_MAPPED) condition instead of (map.m_pblk != NULL_ADDR) to fix this issue. Thanks a lot for the effort of Yi Zhang and Shinichiro Kawasaki on this issue.
