______________________________________________________________________________
		   Caldera International, Inc.  Security Advisory

Subject:		Linux - sendmail instant root exploit
Advisory number: 	CSSA-2001-032.0
Issue date: 		2001, August 24
Cross reference:
______________________________________________________________________________


1. Problem Description

   Sendmail contains an input validation error, so local users may be
   able to write arbitrary data to process memory, possibly allowing
   the execution of code/commands with elevated privileges. This
   allows a local attacker to gain access to the root account.


2. Vulnerable Versions

   System                       Package
   -----------------------------------------------------------
   OpenLinux 2.3                 not vulnerable                
   
   OpenLinux eServer 2.3.1       not vulnerable                
   and OpenLinux eBuilder                                      
   
   OpenLinux eDesktop 2.4        not vulnerable                
   
   OpenLinux Server 3.1          All packages previous to      
                                 sendmail-8.11.1-4
