Summary

CVE-2020-26269 affects TensorFlow release candidate versions 2.4.0rc*, where the general implementation that matches filesystem paths to a globbing pattern can access the array holding the directories out of bounds. The parallel implementation of GetMatchingPaths assumes invariants and preconditions that the PRs #40861 and #44310 never verified. The issue impacts only the master branch and the 2.4 release candidates.

Mitigation

This is patched in version 2.4.0. The final release of the 2.4 release will be patched.
