Unity Linux 20.1070e Security Update: yasm (UTSA-2025-680595)

medium Nessus Plugin ID 267056

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-680595 advisory.

 yasm 1.3.0.55.g101bc was discovered to contain a stack overflow via the component yasm/yasm+0x43b466 in vsprintf. Note: This has been disputed by third parties who argue this is a bug and not a security issue because yasm is a standalone program not designed to run untrusted code.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected yasm package.
