    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.

    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 1.3.9-14.1 of the Debian apache package,
    as well as upstream versions 1.3.16 and 2.0.37. We strongly recommend
    that you upgrade your apache package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
