Immunix 7.0 wu-ftpd format string bug
From: Immunix Security Team <security () wirex com>

-----------------------------------------------------------------------
        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.
