CVE-2020-14938Public exploit

Game crash via unchecked save-file line copy

Published Jun 23, 2020 · Updated Aug 4, 2024

Heap-based buffer overflow in FreedroidRPG 1.0rc2 allows context-dependent attackers to crash the game via a crafted save file. In map.c, decode_map copies an attacker-controlled line exceeding 4,096 bytes into the fixed-size this_line heap buffer without checking nlpos. A user must obtain and load the malicious save, after which the demonstrated consequence is an AddressSanitizer-detected crash.
