CVE-2022-36354Public exploitNetwork attack vector

Heap-data disclosure via unchecked RLE offset

Published Dec 23, 2022 · Updated Apr 14, 2025

Heap out-of-bounds read in OpenImageIO 2.3.19.0 and master-branch-9aeece7a allows attackers to disclose heap data via a malformed RLA file. The decode_rle_span loop increments its encoded-buffer offset after the bounds check, then reads encoded[e] for a positive run without rechecking e against elen. An application must process an attacker-supplied RLA image; each invocation can copy an adjacent heap byte into decoded output, and repeated spans can disclose more data.
