high Nessus Plugin ID 242574

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7661-1 advisory.

 It was discovered that GoBGP did not properly manage memory under certain circumstances, which could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 22.04 LTS and Ubuntu 20.04 LTS. (CVE-2023-46565)

 It was discovered that GoBGP did not properly verify the length of certain inputs. An attacker could possibly use this issue to cause a panic resulting in a denial of service. (CVE-2025-43970, CVE-2025-43971, CVE-2025-43972, CVE-2025-43973)

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 gobgpd and / or golang-github-osrg-gobgp-dev packages.
