bind9 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.04 - Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
Bind could be made to consume resources if it received specially crafted network traffic.
Software Description: - bind9: Internet Domain Name Server
Details:
It was discovered that Bind incorrectly handled limiting the number of simultaneous TCP clients. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service.

The problem can be corrected by updating your system to the following package versions:
Ubuntu 19.04: bind9 1:9.11.5.P1+dfsg-1ubuntu2.3
Ubuntu 18.10: bind9 1:9.11.4+dfsg-3ubuntu5.3
