	Immunix OS Security Advisory

Packages updated:	rxvt
Affected products:	Immunix OS 6.2, 7.0-beta, and 7.0
Bugs fixed:		immunix/1646
Date:			Wed Jun 27 2001
Advisory ID:		IMNX-2001-70-028-01
Author:			Seth Arnold <sarnold@wirex.com>
-----------------------------------------------------------------------

Description:
  Samuel "Zorgon" Dralet has discovered a buffer overflow in rxvt, a
  terminal emulator for X11. This attack is stopped by StackGuard, so
  any exploits can at best kill rxvt; no code can be executed as a
  result of this vulnerability. This release checks the size of a buffer
  before writing data to it, preventing possible DoS attacks against
  rxvt.

  Immunix OS does not ship rxvt setuid or setgid.

  Thanks to Samuel "Zorgon" Dralet for finding the problem and providing
  a solution.
