Vulnerability from variot

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. Provided by Fuji Electric Co., Ltd. V-Server Lite Is an industrial software that collects production information in real time. V-Server Lite To VPR File ( Project file ) Heap-based buffer overflow vulnerability due to too small buffer size allocated when reading (CWE-122) Exists.A remote attacker could elevate privileges and execute arbitrary code. 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
