Debian Security Advisory DSA-133-1                    security@debian.org

Package        : apache-perl
Problem type   : remote DoS / exploit
Debian-specific: no
CVE name       : CAN-2002-0392
CERT advisory  : VU#944335

Mark Litchfield found a denial of service attack in the Apache
web-server. While investigating the problem the Apache Software
Foundation discovered that the code for handling invalid requests which
use chunked encoding also might allow arbitrary code execution.

This has been fixed in version 1.3.9-14.1-1.21.20000309-1 of the Debian
apache-perl package and we recommand that you upgrade your apache-perl
package immediately.

An update for the soon to be released Debian GNU/Linux 3.0/woody
distribution will be available soon.

Debian 2.2 (stable)
- -------------------

  Stable was released for alpha, arm, i386, m68k, powerpc and sparc.
