Echo: openexr: security update to 3.1.13-2

medium Tenable Cloud Security Plugin ID 472889

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 file format, widely used in
 the motion picture industry. In versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.13, the PyOpenEXR
 Python bindings contain a heap out-of-bounds write triggered when reading a crafted deep scanline EXR
 file. When a deep file declares a literal channel named left alongside layer-prefixed RGB channels left.R,
 left.G, and left.B, the wrapper processes the literal left channel first and allocates a scalar deep
 sample array for it, then reuses that same array as the coalesced destination for the prefixed RGB group.
 The deep reader registers sample slices with an RGB stride (three lanes) into storage that was allocated
 with scalar shape, so decoding the deep samples writes past the allocation. Opening such a file through
 the default public Python API, OpenEXR.File(path), causes a heap buffer overflow during normal deep sample
 decode, leading to memory corruption and a crash. This issue is fixed in versions 3.3.13 and 3.4.14.
 (CVE-2026-68514)

Solution

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