Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

This has been fixed in version 1.3.9-14.1-1.21.20000309-1 of the Debian apache-perl package and we recommend 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.
