DESCRIPTION:
SUSE has issued an update for the kernel. This fixes multiple
vulnerabilities, which can be exploited by malicious, local users to
conduct DNS cache poisoning attacks, disclose sensitive information,
bypass certain security restrictions, cause a DoS (Denial of
Service), and potentially gain escalated privileges.
For more information:
SA40691
SA41035
1) An integer overflow within the "btrfs_ioctl_clone" function in
fs/btrfs/ioctl.c can be exploited to e.g. disclose sensitive
information.
2) Incorrect permission checks within the "btrfs_ioctl_clone"
function in fs/btrfs/ioctl.c can be exploited to overwrite
append-only files.
3) An error in the Novell Client novfs /proc interface can be
exploited to cause a DoS (Denial of Service) and potentially execute
code with kernel privileges.
