Technical details
The vulnerability is a buffer overflow triggered during game loading when processing malformed save files or game descriptions. The root cause involves integer overflow and insufficient bounds checking in the save file parser. An attacker can exploit this by crafting a malicious save file that, when loaded by a user, causes the application to crash (denial of service). While the Debian package does not register a media type handler for save files, an attacker could socially engineer a user into opening the malicious file. Patches were released in upstream version 20230122.806ae71.
