CVE-2026-68516

Опубликовано: 24 авг. 2026
Источник: redhat
CVSS3: 6.5

Описание

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. From version 3.4.0 through 3.4.13, a crafted HTJ2K-compressed EXR can crash OpenEXR during normal decode. An HTJ2K-compressed EXR whose JPEG 2000 SIZ fields place the first tile outside the visible image can reach invalid tile and codeblock geometry in the vendored OpenJPH AVX2 decoder, causing a stack out-of-bounds write and denial of service. OpenEXR's HTJ2K path validates the decoded codestream dimensions against the EXR chunk size, but it does not reject SIZ image-offset/tile-grid geometry where the first tile does not intersect the image. This issue is fixed in version 3.4.14.

A flaw was found in OpenEXR. A remote attacker could provide a specially crafted HTJ2K-compressed EXR image file. When OpenEXR processes this file with JPEG 2000 SIZ fields that place the first tile outside the visible image, it can lead to invalid tile and codeblock geometry. This results in a stack out-of-bounds write, causing a denial of service.

Отчет

This vulnerability only affects OpenEXR versions 3.4.0 through 3.4.13, which include HTJ2K compression support. No Red Hat products or Fedora community distributions ship a version within this range.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
