                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name: apache
Advisory ID: MDKSA-2002:068-1
Date: December 18th, 2002
Original Advisory Date: October 15th, 2002
Affected versions: Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

 A number of vulnerabilities were discovered in Apache versions prior to
 1.3.27. The first is regarding the use of shared memory (SHM) in
 Apache. An attacker that is able to execute code as the UID of the
 webserver (typically "apache") is able to send arbitrary processes a
 USR1 signal as root. Using this vulnerability, the attacker can also
 cause the Apache process to continously span more children processes,
 thus causing a local DoS. Another vulnerability was discovered by
 Matthew Murphy regarding a cross site scripting vulnerability in the
 standard 404 error page. Finally, some buffer overflows were found in
 the "ab" benchmark program that is included with Apache.
 
 All of these vulnerabilities were fixed in Apache 1.3.27; the packages
 provided have these fixes applied.
  
Update:

 Packages for SNF7.2 are now available.
