Technical details
The vulnerability is a global buffer overflow in the gf_ac4_parser_bs function (media_tools/av_parsers.c:16140) where the parser accesses AC4_SAMPLE_DELTA_TABLE_48 without proper bounds checking on an attacker-controlled index value. This causes a 4-byte read beyond the global array's boundary when processing a crafted AC4 audio stream. The vulnerability requires a malicious file input but no authentication or user interaction beyond opening the file.
Affected products
