DESCRIPTION:
A vulnerability has been reported in the Linux Kernel, which can be
exploited by malicious, local users to bypass certain security
restrictions.

The vulnerability is caused due to the JFS file system not properly
enforcing xattr namespace access rules, which can be exploited to
bypass the access rules by prefixing valid xattr names with "os2".

SOLUTION:
Update to version 2.4.37.10.
