Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS : nginx vulnerabilities (USN-5722-1)

critical Nessus Plugin ID 167542

Language:

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-5722-1 advisory.

 It was discovered that nginx incorrectly handled certain memory operations in the ngx_http_mp4_module module. A local attacker could possibly use this issue with a specially crafted mp4 file to cause nginx to crash, stop responding, or access arbitrary memory. (CVE-2022-41741, CVE-2022-41742)

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.
