Details

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 LTS and Ubuntu 26.04 LTS. (CVE-2026-43906)
