0/2

Evidence confidence

%47

Short explanation

libaribb24 (aribb24) through version 1.0.3 contains a heap-based buffer overflow vulnerability in src/parser.c via parse_data_unit_statement_body. This issue allows heap memory corruption via oversized caption data units.

Why does it matter?

Attackers can supply crafted caption PES packets in media files or broadcast streams to crash applications like FFmpeg or VLC and possibly corrupt further memory.

What should be done?

Follow vendor advisories
Exercise caution due to unverified patch status
Filter untrusted input in media streams
