(Apache mod_python Denial of Service vulnerability)

    The Apache Foundation has reported that mod_python may be prone to
    Denial of Service attacks when handling a malformed
    query. Mod_python 2.7.9 was released to fix the vulnerability,
    however, because the vulnerability has not been fully fixed,
    version 2.7.10 has been released.
    Users of mod_python 3.0.4 are not affected by this vulnerability.
  
Impact :

    Although there are no known public exploits known for this
    exploit, users are recommended to upgrade mod_python to ensure the
    security of their infrastructure.
  
Workaround :

    Mod_python 2.7.10 has been released to solve this issue; there is
    no immediate workaround."
