Echo: openexr: security update to 3.1.13-2

high Tenable Self-Hosted Container Security Plugin ID 465919

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenEXR is the reference implementation and specification for the EXR image format, widely used in the
 motion picture industry. In versions 3.4.0 through 3.4.11, an integer overflow in ht_undo_impl() in
 src/lib/OpenEXRCore/internal_ht.cpp leads to a heap-buffer overflow when decoding a crafted
 HTJ2K-compressed EXR file. decode->channels[i].width (int32_t) is multiplied by bytes_per_element in
 32-bit signed arithmetic. With large widths (e.g., >= 536870912 for FLOAT data), this overflows, producing
 a corrupted offset that is later used for pointer arithmetic and can cause a heap out-of-bounds write. The
 same unchecked multiplication pattern appears in two other HTJ2K paths (bytes-per-line accumulation and
 pixel-line pointer advancement). As with related CVE-2026-34378 through CVE-2026-34589 fixes in other
 codecs, validating only after the multiplication is too late because the value may already be overflowed.
 This issue has been fixed in version 3.4.12. (CVE-2026-44663)

Solution

Update the openexr library and its related packages to version 3.1.13-2 or later.
