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

high Tenable Cloud Security Plugin ID 457644

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, IDManifest::init() reconstructs strings from a prefix-compressed representation.
 If the previous string is longer than 255 bytes, the next string is expected to begin with a 2-byte prefix
 length. The code reads stringList[i][0] and stringList[i][1] without checking that the current string has
 at least two bytes. This issue has been patched in versions 3.2.9, 3.3.11, and 3.4.11. (CVE-2026-42216)

Solution

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