Summary
Arm Whois 3.11 has a stack-based buffer overflow vulnerability that allows remote attackers to execute arbitrary code by supplying oversized input to the IP address or domain field. Attackers can craft malicious input exceeding 658 bytes with shellcode to overwrite the structured exception handler and gain command execution.
Risk Assessment
This vulnerability allows remote code execution without authentication, potentially leading to full system compromise.
Recommendation
Upgrade Arm Whois to a version containing the fix, or discontinue use of the vulnerable version.
