Vulnerability details
The vulnerability allows a remote attacker to cause OpenSSL to crash.
The vulnerability exists due to a flaw in SSL/TLS handshaking code when using Kerberos ciphersuites. A remote unauthenticated attacker can perform a carefully crafted SSL/TLS handshake against a server configured to use Kerberos ciphersuites in such a way as to cause OpenSSL to crash.
Successful exploitation of this vulnerability may result in a denial of service.
