   An update that fixes two vulnerabilities is now available.

Description:

   This update for bind fixes the following issues:

   - An attacker with the ability to send and receive messages to an
     authoritative DNS server was able to circumvent TSIG authentication of
     AXFR requests. A server that relied solely on TSIG keys for protection
     could be manipulated into (1) providing an AXFR of a zone to an
     unauthorized recipient and (2) accepting bogus Notify packets.
     [bsc#1046554, CVE-2017-3142]

   - An attacker who with the ability to send and receive messages to an
     authoritative DNS server and who had knowledge of a valid TSIG key name
     for the zone and service being targeted was able to manipulate BIND into
     accepting an unauthorized dynamic update. [bsc#1046555, CVE-2017-3143]

   This update was imported from the SUSE:SLE-12-SP1:Update update project.
