Description
An out-of-bounds read vulnerability exists in gbsplay through version 0.0.103 in the mapper_map() function. This flaw allows crafted .gbr, .gbs, or .gb files with malicious ROM bank indexes to cause the player to read beyond the allocated heap buffer, potentially crashing the application.
