Problem description

The ISC, authors of the BIND domain name server, have published
two advisories on vulnerabilities in the BIND8 name
server.

There is a buffer overflow in the way named handles SIG records. This buffer overflow can be exploited to obtain access to the victim host under the account the named process is running with. In all SuSE products, named is configured to run as used "named".
There are several Denial Of Service problems in BIND8 that allow remote attackers to terminate the named process.

Both vulnerabilities are addressed by this update, using patches provided by ISC.

Solution

Please install the updates provided at the location noted below.
