CVE-2014-125011

Process crash via overflowing ANSI escape argument

Published Jun 18, 2022 · Updated Apr 15, 2025

Integer overflow in FFmpeg 2.0's ANSI decoder allows attackers to crash the decoding process with crafted ANSI art data. The decode_frame parser multiplies an unbounded numeric escape-sequence argument by 10 until it overflows; the upstream fix caps the value before multiplication. Exploitation requires FFmpeg or a consuming application to decode attacker-controlled ANSI art, and the demonstrated consequence is an out-of-bounds read and segmentation-fault process crash.
