Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS : systemd vulnerabilities (USN-5928-1)

medium Nessus Plugin ID 172227

Synopsis

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

Description

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 packages.
