Reported to bugtraq on April 20th, a security vulnerability has been
found in the Linux kernel in the ip_setsockopt() function code which
can allow privilege escalation. Code affects kernel versions 2.4.22 -
2.4.25, 2.6.1 - 2.6.3. I think, it also affects the kernel shipped
with Fedora Core 1 which contained a backported version of the
Red Hat Enterprise Linux has #121314 for the same issue.
Thanks for fixing this issue with the latest update :)
