Arm Whois 3.11 contains a buffer overflow vulnerability that allows local attackers to execute arbitrary code by overwriting the structured exception handler. Attackers can craft a malicious input file with a 672-byte offset to overwrite the nSEH and SEH pointers, enabling code execution through exception handler hijacking.
