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.
