USN-3420-1

Summary: linux, linux-aws, linux-gke, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities

Details: It was discovered that a buffer overflow existed in the Bluetooth stack of the Linux kernel when handling L2CAP configuration responses. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-1000251) It was discovered that the Flash-Friendly File System (f2fs) implementation in the Linux kernel did not properly validate superblock metadata. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-10663) It was discovered that a buffer overflow existed in the ioctl handling code in the ISDN subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-12762) Pengfei Wang discovered that a race condition existed in the NXP SAA7164 TV Decoder driver for the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-8831)
