Title
mackron / miniaudio Out-of-Bounds Read in BEXT Coding History Parsing
Summary
miniaudio version 0.11.25 and earlier contain a heap out-of-bounds read vulnerability in the WAV BEXT metadata parser that allows attackers to trigger memory access violations by processing crafted WAV files. Attackers can exploit improper null-termination handling in the coding history field to cause out-of-bounds reads past the allocated metadata pool, resulting in application crashes or denial of service.
Severity ?
5.1 (Medium)
