Descriptions

Fuji Electric V-Server Lite all versions prior to 4.0.9.0 contains a heap based buffer overflow. The buffer allocated to read data, when parsing VPR files, is too small.

Fuji Electric V-Server Lite todas las versiones anteriores a 4.0.9.0, contiene un desbordamiento de búfer en la región heap de la memoria. El búfer asignado para leer datos, cuando se analizan archivos VPR, es muy pequeño.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric V-Server 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 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.
