CVE-2026-110597 [MEDIUM] – Tinyexr through 3.2.0 contains a heap out-of-bounds read vulnerability in ParseEXRMultipar

Tinyexr through 3.2.0 contains a heap out-of-bounds read vulnerability in ParseEXRMultipartHeaderFromMemory() that allows attackers to read beyond buffers due to a stale remaining-size value. Attackers can supply a crafted multi-part EXR file whose later part headers bypass ReadAttribute() bounds checks, crashing applications or leaking adjacent heap memory into attribute values.
