Ubuntu 18.04 LTS / 20.04 LTS : Bind vulnerabilities (USN-5332-1)

medium Nessus Plugin ID 159059

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5332-1 advisory.

 Xiang Li, Baojun Liu, Chaoyi Lu, and Changgen Zou discovered that Bind incorrectly handled certain bogus NS records when using forwarders. A remote attacker could possibly use this issue to manipulate cache results. (CVE-2021-25220)

 It was discovered that Bind incorrectly handled certain crafted TCP streams. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. This issue only affected Ubuntu 21.10. (CVE-2022-0396)

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.
