Echo: openexr: security update to 3.1.13-2+e6

medium Tenable Self-Hosted Container Security Plugin ID 459059

Description

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

 - OpenEXR 3.4.14 contains a NULL Pointer Dereference in the C++ attribute parsing path. A specially crafted
 EXR file containing an unknown-type attribute with dataSize set to zero causes the parser to create an
 opaque attribute with a NULL packed_data pointer. The OpaqueAttribute constructor passes the NULL pointer
 to memcpy() without validating the zero-size condition, resulting in undefined behavior and process
 termination, leading to denial of service. (CVE-2026-88384)

Solution

Update the openexr library and its related packages to version 3.1.13-2+e6 or later.
