"According to its self-reported version number, the Oracle GlassFish
Server running on the remote host is 2.1.1.x prior to 2.1.1.29. It is,
therefore, affected by a remote code execution vulnerability in the
Mozilla Network Security Services (NSS) component due to improper
validation of user-supplied input when parsing ASN.1 structures. An
unauthenticated, remote attacker can exploit this, via crafted ASN.1
data in an X.509 certificate, to cause a heap-based buffer overflow,
resulting in a denial of service condition or the execution of
arbitrary code.");
