Service libraries. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CVE-2009-2404
    Moxie Marlinspike discovered that a buffer overflow in
    the regular expression parser could lead to the
    execution of arbitrary code.

  - CVE-2009-2408
    Dan Kaminsky discovered that NULL characters in
    certificate names could lead to man-in-the-middle
    attacks by tricking the user into accepting a rogue
    certificate.

  - CVE-2009-2409
    Certificates with MD2 hash signatures are no longer
    accepted since they're no longer considered
    cryptograhically secure."
