Descriptions

In Fuji Electric V-Server 4.0.6 and prior, several heap-based buffer overflows have been identified, which may allow an attacker to remotely execute arbitrary code.

En Fuji Electric V-Server versión 4.0.6 y anteriores, se han identificado varios desbordamientos de búfer en la región heap de la memoria, lo que puede permitir a un atacante ejecutar código arbitrario remotamente.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric V-Server. 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 processing of VPR files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
