Immunix OS Security Advisory
Packages updated: wu-ftpd
Affected products: Immunix 7.0
Bugs fixed: immunix/1865
Date: Thu Nov 29 2001
Advisory ID: IMNX-2001-70-036-02
Author: Seth Arnold <sarnold@wirex.com>
-----------------------------------------------------------------------
Description:
This is a re-release of wu-ftpd. New patches are available today that
fix several format string problems, believed to be not exploitable.
There is also a null-pointer dereference check added in several
places, also believed to be not exploitable.
As such, we believe this to be a reliability update only in comparison
to the update in advisory IMNX-2001-70-036-01 -- however, the bug in
yesterday's advisory was at one time believed to be not exploitable as
well. As such, installing this update is a good idea, but not critical
at this point.
It cannot be stressed enough that at least one of IMNX-2001-70-036-01
or IMNX-2001-70-036-02 must be applied quickly; it is rumored this
flaw is being actively exploited.
