Name of the Vulnerable Software and Affected Versions: PrusaSlicer versions 2.2.0 and Master (commit 4b040b856)

Description: A stack-based buffer overflow issue exists in the Objparser::objparse() functionality. This can be triggered by a specially crafted obj file, potentially leading to code execution. An attacker can exploit this by providing a malicious file.

Recommendations: For PrusaSlicer version 2.2.0, consider disabling the Objparser::objparse() function until a patch is available. For PrusaSlicer Master (commit 4b040b856), restrict the use of the Objparser::objparse() functionality to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
