high Nessus Plugin ID 204962

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6909-2 advisory.

 USN-6909-1 fixed several vulnerabilities in Bind. This update provides the corresponding update for Ubuntu 18.04 LTS.

 Original advisory details:

 Toshifumi Sakaguchi discovered that Bind incorrectly handled having a very

 large number of RRs existing at the same time. A remote attacker could

 possibly use this issue to cause Bind to consume resources, leading to a

 denial of service. (CVE-2024-1737)

 It was discovered that Bind incorrectly handled a large number of SIG(0)

 signed requests. A remote attacker could possibly use this issue to cause

 Bind to consume resources, leading to a denial of service. (CVE-2024-1975)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
