A flaw was found in bind. The SPNEGO implementation used by BIND, which is a negotiation mechanism used by GSSAPI to support the secure exchange of keys used to verify the authenticity of communications between parties on a network, is subject to a buffer overflow attack. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
This vulnerability only affects servers configured to use GSS-TSIG, most often to sign dynamic updates. If another mechanism can be used to authenticate updates, the vulnerability can be avoided by choosing not to enable the use of GSS-TSIG features.
