Executive Summary
xwpe 1.5.30a-2.1 and prior contains a stack-based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying overly long input strings that exceed buffer boundaries. Attackers can craft malicious command-line arguments with 262 bytes of junk data followed by shellcode to overwrite the instruction pointer and achieve code execution or denial of service.
