Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 : FRR vulnerabilities (USN-7230-2)

high Nessus Plugin ID 214670

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7230-2 advisory.

Iggy Frankovic discovered that FRR incorrectly handled certain BGP messages. A remote attacker could possibly use this issue to cause FRR to crash, resulting in a denial of service. This issue only affected Ubuntu 20.04 LTS. (CVE-2024-44070)

It was discovered that FRR re-validated all routes in certain instances when the internal socket's buffer size overflowed. A remote attacker could possibly use this issue to impact the performance of FRR, resulting in a denial of service. (CVE-2024-55553)

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.
