Echo: openexr: security update to 3.1.13-2

high Tenable Cloud Security Plugin ID 472882

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. Versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.13 contain a heap buffer
 overflow in PyOpenEXR triggered by a channel-name key collision between literal and prefixed RGB channels.
 When separate_channels=false, PyOpenEXR maps each physical channel name through channelNameToRGBA() and
 coalesces the results into a shared RGB array. A crafted flat scanline EXR that contains both a literal
 channel such as left and prefixed channels such as left.R, left.G, and left.B causes these names to
 collide, so the wrapper reuses an undersized two-dimensional NumPy array for the coalesced RGB slices and
 writes out of bounds when OpenEXR.File(path) decodes the pixels. This issue is fixed in versions 3.3.13
 and 3.4.14. (CVE-2026-68513)

Solution

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