Description
Gbsplay through 0.0.103 contains a heap out-of-bounds read vulnerability in gbr_open() in gbs.c that fails to verify file length before scanning the GBR ROM title field. Attackers can supply a crafted GBR file of 0x21 to 0x162 bytes to read past the heap buffer, crashing gbsplay or leaking memory.
