In FRRouting (FRR) through 9.1, it is possible for the get_edge() function in ospf_te.c in the OSPF daemon to return a NULL pointer. In cases where calling functions do not handle the returned NULL value, the OSPF daemon crashes, leading to denial of service.

The version of frr installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-34088 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1971-1 advisory.

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.
