GLSA-202405-04 : systemd: Multiple Vulnerabilities

medium Nessus Plugin ID 194972

Description

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.

Solution

All systemd users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=sys-apps/systemd-252.4
