OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a heap-based buffer overflow in the HEIF decoder of OpenImageIO allows out-of-bounds writes via crafted images due to a subimage metadata mismatch, leading to memory corruption and potential code execution. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.

CVE-2026-43903 [HIGH] OpenImageIO vulnerabilities
Title: OpenImageIO vulnerabilities
Summary: Several security issues were fixed in OpenImageIO.
It was discovered that OpenImageIO incorrectly performed bounds
checking when processing SGI files. An attacker could possibly
use this issue to cause a denial of service or execute arbitrary
code. (CVE-2026-43903)
It was discovered that OpenImageIO incorrectly handled run-length
encoding when processing Softimage PIC files. An attacker
could possibly use this issue to cause a denial of service or
execute arbitrary code. (CVE-2026-43904)
It was discovered that OpenImageIO incorrectly validated subimage
metadata when processing HEIF files. An attacker could
possibly use this issue to cause a denial of service or execute
arbitrary code. This issue only affected Ubuntu 20.04 LTS, Ubuntu
24.04 LT
