"CVE-2009-0696 bind: DoS (assertion failure) via nsupdate packets

A flaw was found in the way BIND handles dynamic update message
packets containing the 'ANY' record type. A remote attacker could use
this flaw to send a specially crafted dynamic update packet that could
cause named to exit with an assertion failure. (CVE-2009-0696)

Note: even if named is not configured for dynamic updates, receiving
such a specially crafted dynamic update packet could still cause named
to exit unexpectedly.

This update also fixes the following bug :

  - the following message could have been logged:
    'internal_accept: fcntl() failed: Too many open files'.
    With these updated packages, timeout queries are aborted
    in order to reduce the number of open UDP sockets, and
    when the accept() function returns an EMFILE error
    value, that situation is now handled gracefully, thus
    resolving the issue. (BZ#498164)

After installing the update, the BIND daemon (named) will be restarted
automatically."
