Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS : FFmpeg vulnerabilities (USN-8469-1)

critical Nessus Plugin ID 322791

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8469-1 advisory.

 Jiasheng Jiang discovered that FFmpeg incorrectly handled memory in certain error-handling paths of its TensorFlow DNN backend. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2025-12343)

 Quang Luong discovered that FFmpeg incorrectly handled certain subsample data. An attacker could possibly use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2026-40962)

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.
