Description Mark J. Cox 2004-02-16 08:49:49 EST

Paul Starzetz discovered a flaw in return value checking in mremap()
in the Linux kernel versions 2.4.24 and previous that may allow a
local attacker to gain root privileges. No exploit is currently
available; however this issue may be exploitable. 

Affected: 3

Embargoed until Feb18

Comment 1 Ernie Petrides 2004-02-19 16:26:53 EST

The fix for this problem was committed to the RHEL3 U2 patch pool
on 9-Feb-2004, and has been available internally with the build of
kernel version 2.4.21-9.6.EL.

This problem was also fixed in kernel version 2.4.21-9.0.1.EL, which
was just released today on RHN as errata advisory RHSA-2004:066.
