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.
