DESCRIPTION:
SUSE has issued an update for the kernel. This fixes some weaknesses
and vulnerabilities, which can be exploited by malicious, local users
to disclose system and potentially sensitive information, cause a DoS
(Denial of Service), bypass certain security restrictions, conduct
DNS cache poisoning attacks, and gain escalated privileges, and by
malicious people to cause a DoS.

1) Errors within the implementation of the External Data
Representation (XDR) for NFSv4 can be exploited to cause a kernel
crash by sending specially crafted compound requests to the NFSv4
server.

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 integer overflow within the "btrfs_ioctl_clone" function in
fs/btrfs/ioctl.c can be exploited to e.g. disclose sensitive
information.

4) An error within the GFS2 file system when handing certain rename
operations can be exploited to cause a kernel crash.

5) Two vulnerabilities are caused due to integer overflow errors
within the "ext4_ext_in_cache()" and "ext4_ext_get_blocks()"
functions in fs/ext4/extents.c, which can be exploited to e.g.
trigger a "BUG()" when performing certain file operations on certain
configurations of the ext4 file system.

SOLUTION:
Apply updated packages.
