CVE-2014-125022Network attack vector

Media-processing interruption via unpadded Shorten buffer

Published Jun 19, 2022 · Updated Apr 15, 2025

Memory corruption in FFmpeg 2.0 allows remote attackers to interrupt media processing via a crafted Shorten audio bitstream. The shorten_decode_frame function allocates its internal bitstream buffer to max_framesize without FF_INPUT_BUFFER_PADDING_SIZE, permitting decoder reads beyond the allocation. No authentication is required, but a consuming application must decode the attacker-controlled stream; the published impact is limited to availability.
