SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionThe BIND DNS server is vulnerable to the recently-discovered OpenSSL RSA signature verification problem (CVE-2006-4339). BIND uses RSA cryptography as part of its DNSSEC implementation. As a result, to resolve the security issue, these packages need to be upgraded and for both KEY and DNSKEY record types, new RSASHA1 and RSAMD5 keys need to be generated using the '-e' option of dnssec-keygen, if the current keys were generated using the default exponent of 3.
You are able to determine if your keys are vulnerable by looking at the algorithm (1 or 5) and the first three characters of the Base64 encoded RSA key. RSAMD5 (1) and RSASHA1 (5) keys that start with 'AQM', 'AQN', 'AQO', or 'AQP' are vulnerable.
SolutionUpdate the affected bind, bind-devel and / or bind-utils packages.
