Echo: openexr: security update to 3.1.13-2

high Tenable Cloud Security Plugin ID 464270

Description

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

- OpenEXR provides the specification and reference implementation of the EXR file format, an image storage
format for the motion picture industry. From version 3.4.0 to before version 3.4.7, an attacker providing
a crafted .exr file with HTJ2K compression and a channel width of 32768 can write controlled data beyond
the output heap buffer in any application that decodes EXR images. The write primitive is 2 bytes per
overflow iteration or 4 bytes (by another path), repeating for each additional pixel past the overflow
point. In this context, a heap write overflow can lead to remote code execution on systems. This issue has
been patched in version 3.4.7. (CVE-2026-34545)

Solution

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