Echo: openexr: security update to 3.1.13-2+e1

medium Tenable Self-Hosted Container Security Plugin ID 465102

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 versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and
 3.4.0 to before 3.4.11, readVariableLengthInteger() decodes a variable-length integer from untrusted EXR
 input without bounding the shift count. After enough continuation bytes, the code executes a left shift by
 70 on a 64-bit value, which is undefined behavior. This issue has been patched in versions 3.2.9, 3.3.11,
 and 3.4.11. (CVE-2026-42217)

Solution

Update the openexr library and its related packages to version 3.1.13-2+e1 or later.
