GnuTLS -- multiple vulnerabilities

SecurityFocus reports:

GnuTLS is prone to multiple remote vulnerabilities:

• A remote code-execution vulnerability.
• A denial-of-service vulnerability.
• A signature-generation vulnerability.
• A signature-verification vulnerability.

An attacker can exploit these issues to potentially execute arbitrary code, trigger denial-of-service conditions, carry out attacks against data signed with weak signatures, and cause clients to accept expired or invalid certificates from servers.
