Updated kernel packages fixes security vulnerabilities.
The kernel has been updated to the upstream 3.12.21 longterm kernel, and fixes the following security issues:
media-device: fix infoleak in ioctl mediaenumentities() (CVE-2014-1739)
The futexrequeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEXREQUEUE command that facilitates unsafe waiter modification. (CVE-2014-3153)
kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIGAUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number. To avoid this and other issues CONFIGAUDITSYSCALL has been disabled. (CVE-2014-3917)
