Ubuntu 22.04 LTS / 23.10 / 24.04 LTS : FRR vulnerabilities (USN-6794-1)

medium Nessus Plugin ID 198041

Language:

Synopsis

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

Description

The remote Ubuntu 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6794-1 advisory.

 It was discovered that FRR incorrectly handled certain malformed BGP and OSPF packets. A remote attacker could use this issue to cause FRR to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.
