Fedora 36 : systemd (2022-ef4f57b072)

medium Nessus Plugin ID 169431

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2022-ef4f57b072 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)

 - local information leak due to systemd-coredump not respecting fs.suid_dumpable kernel setting [fedora-37] (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.

Solution

Update the affected systemd package.
