Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A heap out-of-bounds read vulnerability exists in the RLA format parser of OpenImageIO master-branch-9aeece7a and v2.3.19.0. More specifically, in the way run-length encoded byte spans are handled. A malformed RLA file can lead to an out-of-bounds read of heap metadata which can result in sensitive information leak. An attacker can provide a malicious file to trigger this vulnerability.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Recommended fix Moderate confidence

OpenImageIO v2.3.20.0 or later (fixed release after v2.3.19.0)

  1. 1. Identify the OpenImageIO version currently installed: dpkg -l | grep openimageio or oiiotool --version
  2. 2. For Debian 11.0 systems, check for available security updates: apt-get update && apt-get upgrade -s | grep openimageio
  3. 3. If a newer fixed version is available in Debian security repositories, upgrade: apt-get update && apt-get install --only-upgrade libopenimageio
  4. 4. If no Debian package update is available, consider building OpenImageIO from source from the master branch after commit 9aeece7a which contains the fix
  5. 5. Verify the fix by running oiiotool --version to confirm the updated version is installed
  6. 6. Test that RLA file processing works correctly with the updated version
Caveat Minor: Upgrading OpenImageIO point releases typically has low risk but may introduce subtle changes in image processing behavior; test critical workflows

Generated from the published advisory — verify against the referenced sources before acting.

No vendor fix exists Debian Linux has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
