Doc Type: Bug Fix
Doc Text:
A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled.

Description Martin Prpič 2015-03-16 10:37:08 EDT 
A malicious client can trigger an OPENSSL_assert (i.e., an abort) in
servers that both support SSLv2 and enable export cipher suites by sending
a specially crafted SSLv2 CLIENT-MASTER-KEY message.

This issue affects OpenSSL versions: 1.0.2, 1.0.1, 1.0.0, and 0.9.8. This issue is fixed in versions: 1.0.2a, 1.0.1m, 1.0.0r, and 0.9.8zf.
