Doc Text:
A NULL pointer dereference flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm. A remote attacker could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication.

Description Huzaifa S. Sidhpurwala 2015-12-04 03:55:36 UTC 
The following was reported by OpenSSL upstream:

The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and absent mask generation function parameter. Since these routines are used to verifycertificate signature algorithms this can be used to crash any certificate verification operation and exploited in a DoS attack. Any application which performs certificate verification is vulnerable including OpenSSL clients and servers which enable client authentication.

This issue affects OpenSSL versions 1.0.2 and 1.0.1.

OpenSSL 1.0.2 users should upgrade to 1.0.2e
OpenSSL 1.0.1 users should upgrade to 1.0.1q

This issue was reported to OpenSSL on August 27 2015 by Loïc Jonas Etienne (Qnective AG). The fix was developed by Dr. Stephen Henson of the OpenSSL development team.
