Official description
A vulnerability has been identified in Solid Edge SE2022 (All versions < V222.0MP12), Solid Edge SE2023 (All versions < V223.0Update2). The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted PAR files. This could allow an attacker to execute code in the context of the current process.
