Description :

Kernel: net: leakage of uninitialized memory to user-space via recv
syscalls (CVE-2013-6405)

Multiple buffer underflows in the XFS implementation in the Linux
kernel through 3.12.1 allow local users to cause a denial of service
(memory corruption) or possibly have unspecified other impact by
leveraging the CAP_SYS_ADMIN capability for a (1)
XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl
call with a crafted length value, related to the
xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the
xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c.
