17th January, 2018
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Bind could be made to crash if it received specially crafted network traffic.
- bind9 - Internet Domain Name Server
Jayachandran Palanisamy discovered that the Bind resolver incorrectly
handled fetch cleanup sequencing. A remote attacker could possibly use this
issue to cause Bind to crash, resulting in a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 17.10:
- bind9 1:9.10.3.dfsg.P4-12.6ubuntu1.1
- Ubuntu 16.04 LTS:
