"Several problems have been discovered in Apache2, the next generation,
scalable, extendable web server. The Common Vulnerabilities and
Exposures project identifies the following problems :

  - CAN-2005-1268
    Marc Stern discovered an off-by-one error in the mod_ssl
    Certificate Revocation List (CRL) verification callback.
    When Apache is configured to use a CRL this can be used
    to cause a denial of service.

  - CAN-2005-2088

    A vulnerability has been discovered in the Apache web
    server. When it is acting as an HTTP proxy, it allows
    remote attackers to poison the web cache, bypass web
    application firewall protection, and conduct cross-site
    scripting attacks, which causes Apache to incorrectly
    handle and forward the body of the request.

  - CAN-2005-2700

    A problem has been discovered in mod_ssl, which provides
    strong cryptography (HTTPS support) for Apache that
    allows remote attackers to bypass access restrictions.

  - CAN-2005-2728

    The byte-range filter in Apache 2.0 allows remote
    attackers to cause a denial of service via an HTTP
    header with a large Range field."
