    Package        : modsecurity-apache
    CVE ID         : CVE-2013-5705
    
    Martin Holst Swende discovered a flaw in the way chunked requests are
    handled in ModSecurity, an Apache module whose purpose is to tighten the
    Web application security. A remote attacker could use this flaw to
    bypass intended mod_security restrictions by using chunked transfer
    coding with a capitalized Chunked value in the Transfer-Encoding HTTP
    header, allowing to send requests containing content that should have
    been removed by mod_security.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 2.6.6-6+deb7u2.
    
    For the testing distribution (jessie), this problem has been fixed in
    version 2.7.7-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.7.7-1.
    
    We recommend that you upgrade your modsecurity-apache packages.
