Vulnerability Advisory : mackron / dr_libs Excessive Memory Allocation in PICTURE Metadata Parsing with LOW Attack Complexity

dr_libs version 0.13.3 and earlier contain an uncontrolled memory allocation vulnerability in drflac__read_and_decode_metadata() that allows attackers to trigger excessive memory allocation by supplying crafted PICTURE metadata blocks. Attackers can exploit attacker-controlled mimeLength and descriptionLength fields to cause denial of service through memory exhaustion when processing FLAC streams with metadata callbacks.
