"The remote host appears to be running a version of Apache that is
prior to 2.0.55. It is, therefore affected by multiple
vulnerabilities :

  - A security issue exists where 'SSLVerifyClient' is not
    enforced in per-location context if 'SSLVerifyClient
    optional' is configured in the vhost configuration.
    (CVE-2005-2700)

  - A denial of service vulnerability exists when processing
    a large byte range request, as well as a flaw in the 
    'worker.c' module which could allow an attacker to force
    this service to consume excessive amounts of memory.
    (CVE-2005-2970)

  - When Apache is acting as a proxy, it is possible for a
    remote attacker to poison the web cache, bypass web 
    application firewall protection, and conduct cross-site
    scripting attacks via an HTTP request with both a 
    'Transfer-Encoding: chunked' header and a 
    'Content-Length' header. (CVE-2005-2088)

  - Multiple integer overflows exists in PCRE in quantifier
    parsing which could be triggered by a local user through
    use of a specially crafted regex in an .htaccess file.
    (CVE-2005-2491)

  - An issue exists where the byte range filter buffers
    responses into memory. (CVE-2005-2728)

  - An off-by-one overflow exists in mod_ssl while printing
    CRL information at 'LogLevel debug' which could be 
    triggered if configured to use a 'malicious CRL'.
    (CVE-2005-1268)");
