Technical details
An out-of-bounds read vulnerability exists in drmp3_init_internal when parsing MPEG frame side information. A truncated MP3 frame causes the bitstream parser to advance past the allocated frame buffer, allowing subsequent reads of the Xing/Info tag identifier to access memory outside the heap-allocated region. The vulnerability is triggered via a malicious MP3 file processed without user interaction restrictions, requiring only network/local file delivery.
