"The version of IBM HTTP Server running on the remote host is affected by a vulnerability. The BN_GF2m_mod_inv function
in crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b does
not properly handle ECParameters structures in which the curve is over a malformed binary polynomial field, which allows
remote attackers to cause a denial of service (infinite loop) via a session that uses an Elliptic Curve algorithm, as
demonstrated by an attack against a server that supports client authentication.

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