Detail

It was discovered that BIND, an implementation of the DNS protocol suite, does not properly check the result of an OpenSSL function which is used to verify DSA cryptographic signatures. As a result, incorrect DNS resource records in zones protected by DNSSEC could be accepted as genuine.

For the stable distribution (etch), this problem has been fixed in version 9.3.4-2etch4.

For the unstable distribution (sid) and the testing distribution (lenny), this problem will be fixed soon.

We recommend that you upgrade your BIND packages.
