vgmstream through r2117 Stack Out-of-Bounds Read via G.722.1/Siren14 Decoder

MEDIUM 4.8EPSS 0.2%

vgmstream through r2117 contains a stack out-of-bounds read vulnerability in the G.722.1/Siren14 decoder in g7221_lib.c, whose bit reader refills without checking the data_u32 array end. Attackers can supply crafted .s14 or .sss files that drive decode_vector_quantized_mlt_indices() past the stack buffer during format detection, crashing the application.
