Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS : PipeWire vulnerabilities (USN-8535-1)

medium Nessus Plugin ID 326799

Synopsis

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

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8535-1 advisory.

 It was discovered that PipeWire accepted unbounded Content-Length values in its RAOP module. A remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2026-14324)

 It was discovered that PipeWire performed multiple unbounded stack allocations in its PulseAudio protocol server. A local attacker could possibly use this issue to cause a denial of service. (CVE-2026-14330)

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.
