The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6807-1 advisory.
It was discovered that FRR incorrectly handled certain network traffic. A remote attacker could possibly use this issue to cause FRR to crash, resulting in a denial of service. (CVE-2022-26126, CVE-2022-26127, CVE-2022-26128, CVE-2022-26129, CVE-2022-37032, CVE-2022-37035, CVE-2023-31490, CVE-2023-38406, CVE-2023-38407, CVE-2023-46752, CVE-2023-46753, CVE-2023-47234, CVE-2023-47235, CVE-2024-31948)
Ben Cartwright-Cox discovered that FRR incorrectly handled certain network traffic. A remote attacker could possibly use this issue to cause FRR to crash, resulting in a denial of service. (CVE-2023-38802)
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.
