The remote host is affected by the vulnerability described in GLSA-202405-04 (systemd: Multiple Vulnerabilities)

  - 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)

  - 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)

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

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

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5928-1 advisory.

    It was discovered that systemd did not properly validate the time and accuracy values provided to the     format_timespan() function. An attacker could possibly use this issue to cause a buffer overrun, leading     to a denial of service attack. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04     LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-3821)

    It was discovered that systemd did not properly manage the fs.suid_dumpable kernel configurations. A local     attacker could possibly use this issue to expose sensitive information. This issue only affected Ubuntu     20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2022-4415)

    It was discovered that systemd did not properly manage a crash with long backtrace data. A local attacker     could possibly use this issue to cause a deadlock, leading to a denial of service attack. This issue only     affected Ubuntu 22.10. (CVE-2022-45873)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:0954 advisory.

    The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and     LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for     starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups.
    In addition, it supports snapshotting and restoring of the system state, maintains mount and automount     points, and implements an elaborate transactional dependency-based service control logic. It can also work     as a drop-in replacement for sysvinit.

    Security Fix(es):

    * systemd: local information leak due to systemd-coredump not respecting fs.suid_dumpable kernel setting     (CVE-2022-4415)

    * systemd: deadlock in systemd-coredump via a crash with a long backtrace (CVE-2022-45873)
