SCA: security update for OpenMcdf (GHSA-jxpf-xq2m-q525)

medium Tenable Cloud Security Plugin ID 440741

Description

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

 - OpenMcdf is a fully .NET / C# library to manipulate Compound File Binary File Format files, also known as
 Structured Storage. Prior to version 3.1.3, OpenMcdf does not detect cycles in the directory entry red-
 black tree of a Compound File Binary (CFB) document. A crafted CFB file with a cycle in the LeftSiblingID
 / RightSiblingID chain causes Storage.EnumerateEntries() and Storage.OpenStream() to loop indefinitely,
 consuming the calling thread with no possibility of recovery via try/catch. This issue has been patched in
 version 3.1.3. (CVE-2026-41511)

Solution

Update the OpenMcdf library and its related packages to version 3.1.3 or later.
