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]

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
