OpenSSL Resource Management Errors Vulnerability - CVE-2015-1788

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.
