Updated squirrel/supertux packages fix security vulnerability

Publication date: 24 Apr 2023
Type: security
Affected Mageia releases : 8
CVE: CVE-2021-41556


sqclass.cpp in Squirrel 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)

supertux has been rebuilt as it uses a bundled copy of squirrel.
