The Dev was the first of several zillion to point out that security holes were found in BIND. The detailed table of known vulnerabilities will help clarify (and it has tarball links too), but the short version is, if you're running BIND 4 or BIND 8, set aside some time today to upgrade to 4.9.8 or 8.2.3 (not beta, betas of 8.2.3 are vulnerable). And now's a good time to reconsider version 9, too. SecurityFocus warns that the last time a BIND hole of this magnitude was found, it was followed by a "cyber-crime wave." Exploits for these holes were successfully created by COVERT Labs, but nobody seems to know whether they're in the wild yet. Obviously, they soon will be. Post your questions and answers about upgrading below.
