The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6432-1 advisory.

  • An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c processes NLRIs if the attribute length is zero. (CVE-2023-41358)

  • An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c can read the initial byte of the ORF header in an ahead-of-stream situation. (CVE-2023-41360)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
