Summary: Security update for kernel-source-rt

Details: The SUSE Linux Enterprise 11 SP4 Realtime kernel was updated to version 3.0.101.rt130-45.1 to receive various security and bugfixes. Following security bugs were fixed: * CVE-2015-6252: Possible file descriptor leak for each VHOST_SET_LOG_FDcommand issued, this could eventually wasting available system resources and creating a denial of service (bsc#942367). * CVE-2015-5707: Possible integer overflow in the calculation of total number of pages in bio_map_user_iov() (bsc#940338). * CVE-2015-5364: The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 do not properly consider yielding a processor, which allowed remote attackers to cause a denial of service (system hang) via incorrect checksums within a UDP packet flood (bnc#936831). * CVE-2015-5366: The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 provide inappropriate -EAGAIN return values, which allowed remote attackers to cause a denial of service (EPOLLET epoll application read outage) via an incorrect checksum in a UDP packet, a different vulnerability than CVE-2015-5364 (bnc#936831). * CVE-2015-1420: Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allowed local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function (bnc#915517). * CVE-2015-4700: The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allowed local users to cause a denial of service (system crash) by creating a packet filter and then loading crafted BPF instructions that trigger late convergence by the JIT compiler (bnc#935705). * CVE-2015-5697: The get_bitmap_file function in drivers/md/md.c in the Linux kernel before 4.1.6 does not initialize a certain bitmap data structure, which allows local users to obtain sensitive information from kernel memory via a GET_BITMAP_FILE ioctl call.
