"Multiple vulnerabilities has been found and corrected in the Linux
kernel :

The compat_sys_recvmmsg function in net/compat.c in the Linux kernel
before 3.13.2, when CONFIG_X86_X32 is enabled, allows local users to
gain privileges via a recvmmsg system call with a crafted timeout
pointer parameter (CVE-2014-0038).

The restore_fpu_checking function in
arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8
on the AMD K7 and K8 platforms does not clear pending exceptions
before proceeding to an EMMS instruction, which allows local users to
cause a denial of service (task kill) or possibly gain privileges via
a crafted application (CVE-2014-1438).

The yam_ioctl function in drivers/net/hamradio/yam.c in the Linux
kernel before 3.12.8 does not initialize a certain structure member,
which allows local users to obtain sensitive information from kernel
memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG
ioctl call (CVE-2014-1446).

The updated packages provides a solution for these security issues."
