CVE-2022-32406Public exploit

Map compiler crash via oversized shader image name

Published Jul 14, 2022 · Updated Aug 3, 2024

Buffer overflow in q3map2 in GtkRadiant 1.6.6 allows attackers to crash the map compiler via a crafted MAP file. During MAP parsing, ParseBrush passes an oversized shader image name to sprintf or strcpy without bounding it to the 64-byte destination. The user must run q3map2 on the malicious file; the demonstrated consequence is process termination, not code execution or data exposure.
