Endor patches is a curated repository of software packages with backported vulnerability fixes for your security and convenience. Endor Labs identifies vulnerable functions and the commits that fixed each vulnerability in the open-source community. These fixes, along with necessary supporting commits, are applied to older software versions to create a minimum viable security patch for each library supported by Endor Labs. Endor patches are a result of extensive research. In security, trust is crucial. Therefore, the patch details are fully transparent. The builds are hermetic ensuring they are consistent, reproducible, and reliable. The exact code changes, along with builds, build steps, and logs, are auditable and available for review. Customers can access Endor patches through a hosted repository, where each software component has three types of versions.
  • A version associated with a specific patch date for build reproducibility. For instance: v2.9.10.3-endor-2024-07-11.
  • A version with the latest patched version of a library, incorporating all current patches. This can be used by appending -endor-latest to a package version. For instance: v2.9.10.3-endor-latest.
  • A version matching the upstream open-source version, allowing users to use the patched version without code changes. For instance: v2.9.10.3.
By minimizing changes to fix known vulnerabilities and providing complete transparency, Endor Patches offer a comprehensive solution to help teams quickly address vulnerabilities, even when a fix is challenging. The following sections provide detailed information on how to use Endor patches.
