CVE-2021-38421

Fuji Electric V-Server Lite y Tellus Lite V-Simulator versiones anteriores a 4.0.12.0, son vulnerables a una lectura fuera de límites, lo que puede permitir a un atacante leer información confidencial de otras ubicaciones de memoria o causar un bloqueo

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric Tellus Lite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of V8 files within the V-Simulator module. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
