OpenSSL on a server configured with Kerberos ciphersuites denial of service

openssl-kerberos-ciphersuites-dos (15508) The risk level is classified as MediumMedium Risk

Description:

OpenSSL is vulnerable to a denial of service. If a server is configured to use Kerberos ciphersuites, a remote attacker can send a specially-crafted handshake to a server that uses the OpenSSL library to cause OpenSSL to crash.

Note: Any application that uses the OpenSSL's SSL/TLS library may be vulnerable.


Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of OpenSSL (0.9.7d or 0.9.6m), as listed in OpenSSL Security Advisory [17 March 2004]. See References.

Recompile applications that are statically linked to OpenSSL libraries.
