Subject: [linsec] ImmunixOS 7.0 sendmail update
Date: Fri, 24 Aug 2001 17:25:34 -0700
-----------------------------------------------------------------------
Immunix OS Security Advisory
Packages updated: sendmail
Affected products: Immunix OS 7.0
Bugs fixed: immunix/1615, immunix/1690
Date: Thu Aug 23 2001
Advisory ID: IMNX-2001-70-032-01
Author: Seth Arnold <sarnold@wirex.com>
-----------------------------------------------------------------------
Description:
This update fixes two problems with sendmail. The first is a fairly
serious problem handing command line arguments that can lead to root
privileges, discovered by Cade Cairns. The second is a race condition
with the signal handling, discovered by Michal Zalewski, with root
access a possibility.
StackGuard protection from the first problem is minimal -- while it
may prevent trivial exploits from running, StackGuard should not be
counted an effective defense against this problem.
We recommend users upgrade their sendmail as soon as possible. While
Immunix OS 6.2 sendmail is not vulnerable to this problem (per Dave
Ahmed's bugtraq post), we have not researched this issue -- Immunix OS
6.2 is no longer officially supported.
