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 recommand that you upgrade your apache-ssl package
