Original NVD Description

Mapscrn 2.0.3 contains a stack-based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an oversized input buffer. Attackers can craft a malicious buffer with junk data, return address, NOP instructions, and shellcode to overflow the stack and achieve code execution or denial of service.
