high Nessus Plugin ID 321364

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8438-1 advisory.

 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)

 It was discovered that OpenImageIO contained multiple integer overflow vulnerabilities when processing DPX files. An attacker could possibly use these issues to cause a denial of service or execute arbitrary code.
 (CVE-2026-43907, CVE-2026-43908, CVE-2026-43909)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
