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
There exists a stack buffer overflow in libjxl. A specifically-crafted file can cause the JPEG XL decoder to use large amounts of stack space (up to 256mb is possible, maybe 512mb), potentially exhausting the stack. An attacker can craft a file that will cause excessive memory usage. We recommend upgrading past commit 65fbec56bc578b6b6ee02a527be70787bbd053b0.

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.

dbcve analysis
How this class of weakness works · CWE-400

A single request can consume unbounded CPU, memory, or connections, so a modest amount of malicious traffic exhausts the service. The result is denial of service for everyone else. Remediation is enforcing limits, quotas, and timeouts on what any one request can use.

Recommended fix High confidence

libjxl 0.8.4 or later (or commit 65fbec56bc578b6b6ee02a527be70787bbd053b0 and beyond)

  1. 1. Identify the current version of libjxl in your project by checking your dependency configuration (e.g., package.json, requirements.txt, CMakeLists.txt, or git submodule)
  2. 2. Update your dependency to libjxl version 0.8.4 or later. For example: if using CMake, update the git reference or submodule to a tag >= 0.8.4; if using a package manager, update the package version constraint
  3. 3. Rebuild your project to incorporate the updated libjxl library
  4. 4. Test that your application correctly handles JPEG XL files after the upgrade
Caveat Review the libjxl 0.8.4 release notes for any API/ABI changes that may affect your integration
