Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: ghostscript (UTSA-2026-142364)

high Nessus Plugin ID 370109

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-2026-142364 advisory.

 A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process.
 The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime. An attacker can deliver the document directly or through formats that delegate rendering to Ghostscript (for example EPS import or print conversion workflows). Successful exploitation can compromise confidentiality, integrity, and availability of data accessible to the process running Ghostscript.

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 ghostscript package.
