  - CVE-2010-0408
    mod_proxy_ajp would return the wrong status code if it
    encountered an error, causing a backend server to be put
    into an error state until the retry timeout expired. A
    remote attacker could send malicious requests to trigger
    this issue, resulting in denial of service.

  - CVE-2010-0434
    A flaw in the core subrequest process code was found,
    which could lead to a daemon crash (segfault) or
    disclosure of sensitive information if the headers of a
    subrequest were modified by modules such as mod_headers."
