Multiple vulnerabilities have been identified in BIND, which is used in virtually any unix flavour and linux distribution.

All BIND 8 versions up to and including 8.3.3 as well as all BIND 4 versions up to and including 4.9.10 suffer a remotely exploitable buffer overflow. This can be exploited on any DNS server, which allows recursive DNS (default behaviour). When BIND constructs a response, which contains a SIG record, a buffer overflow can be triggered making it possible to execute arbitrary code with the privileges of named.

BIND 8 versions 8.3.0 up to and including 8.3.3 suffer a remotely exploitable Denial of Service, which can be exploited by making a client request a non-existent subdomain of a valid domain name.

BIND 8 versions up to and including 8.3.3 suffer a Denial of Service vulnerability, which can be exploited if an invalid expiry time is supplied.

BIND 4.9.2 through 4.9.10 suffer a buffer overflow in LIBRESOLV. This does not affect BIND as such, but it does affect derived resolver libraries using the functions getnetbyname() and getnetbyaddr().

Solution
Currently, only RedHat has issued an update but other vendors should follow shortly.
