Description Mark J. Cox (Product Security) 2004-04-20 08:35:04 EDT
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.  It also affects the kernel shipped with Red
Hat Enterprise Linux 3 which contained a backported version of the
vulnerable code.

The fixes for this problem have been committed to the E2 patch pool

(in kernel version 2.4.21-15.EL).
