openSUSE 15 Security Update : squirrel (openSUSE-SU-2023:0080-1)

critical Nessus Plugin ID 173383

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2023:0080-1 advisory.

 - sqclass.cpp in Squirrel through 2.2.5 and 3.x through 3.1 allows an out-of-bounds read (in the core interpreter) that can lead to Code Execution. If a victim executes an attacker-controlled squirrel script, it is possible for the attacker to break out of the squirrel script sandbox even if all dangerous functionality such as File System functions has been disabled. An attacker might abuse this bug to target (for example) Cloud services that allow customization via SquirrelScripts, or distribute malware through video games that embed a Squirrel Engine. (CVE-2021-41556)

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 squirrel, squirrel-devel, squirrel-devel-static and / or squirrel-examples packages.
