From: Immunix Security Team 
Subject: Immunix OS 7.0 wu-ftpd update

-----------------------------------------------------------------------
        Immunix OS Security Advisory

Packages updated:       wu-ftpd
Affected products:      Immunix 7.0
Bugs fixed:             immunix/1861
Date:                   Wed Nov 28 2001
Advisory ID:            IMNX-2001-70-036-01
Author:                 Seth Arnold 
-----------------------------------------------------------------------

Description:
  CORE Security Technologies has found an heap overflow problem in
  wu-ftpd, related to the internal globbing functions. Because this is a
  heap overflow, StackGuard does not prevent any possible exploits from
  working.

  Thomas Biege from SuSE has also discovered several format-string
  problems that may or may not be remotely exploitable; these problems
  were also found independently by someone else, who sadly is unknown to
  WireX.

  The wu-ftpd packages provided here fix these problems, as well as
  other lesser problems.
