Ubuntu 20.04 LTS / 22.04 LTS / 23.04 : Bind vulnerabilities (USN-6183-1)

high Nessus Plugin ID 177476

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6183-1 advisory.

Shoham Danino, Anat Bremler-Barr, Yehuda Afek, and Yuval Shavitt discovered that Bind incorrectly handled the cache size limit. A remote attacker could possibly use this issue to consume memory, leading to a denial of service. (CVE-2023-2828)

It was discovered that Bind incorrectly handled the recursive-clients quota. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 22.10, and Ubuntu 23.04. (CVE-2023-2911)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
