The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-0954 advisory.

  - systemd 250 and 251 allows local users to achieve a systemd-coredump deadlock by triggering a crash that     has a long backtrace. This occurs in parse_elf_object in shared/elf-util.c. The exploitation methodology     is to crash a binary calling the same function recursively, and put it in a deeply nested directory to     make its backtrace large enough to cause the deadlock. This must be done 16 times when MaxConnections=16     is set for the systemd/units/systemd-coredump.socket file. (CVE-2022-45873)

  - A vulnerability was found in systemd. This security flaw can cause a local information leak due to     systemd-coredump not respecting the fs.suid_dumpable kernel setting. (CVE-2022-4415)

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

The version of systemd 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-2022-45873 advisory.
