CVE-2016-3182

Process crash via eSYCC conversion buffer overflow

Published Feb 20, 2020 · Updated Aug 5, 2024

Heap-buffer overflow in color_esycc_to_rgb in OpenJPEG before 2.1.1 allows attackers to crash an image-decoding process via a crafted JPEG 2000 file. The conversion loop reads four bytes beyond an allocated component buffer, corrupting heap state that later fails during deallocation. Exploitation requires a user or application to decode attacker-controlled image content; the demonstrated consequence is process termination, not code execution.
