Security database references:

More information:

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 on 64 bit architectures.

This has been fixed in version 1.3.9.13-4.1 of the Debian apache-ssl package and we recommend that you upgrade your apache-ssl package immediately.

An update for the soon to be released Debian GNU/Linux 3.0/woody distribution is not available at the moment.

Fixed in:

Debian GNU/Linux 2.2 (potato)
