  - Heap-based buffer overflow in a regular-expression parser in Mozilla Network Security Services (NSS)
    before 3.12.3, as used in Firefox, Thunderbird, SeaMonkey, Evolution, Pidgin, and AOL Instant Messenger
    (AIM), allows remote SSL servers to cause a denial of service (application crash) or possibly execute
    arbitrary code via a long domain name in the subject's Common Name (CN) field of an X.509 certificate,
    related to the cert_TestHostName function. (CVE-2009-2404)

  - Mozilla Network Security Services (NSS) before 3.12.3, Firefox before 3.0.13, Thunderbird before 2.0.0.23,
    and SeaMonkey before 1.1.18 do not properly handle a '\0' character in a domain name in the subject's
    Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof
    arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority. NOTE: this
    was originally reported for Firefox before 3.5. (CVE-2009-2408)

  - The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and
    2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might
    allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in
    less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of
    computation required is still large. (CVE-2009-2409)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
