USN-8477-1 fixed a vulnerability in tar. The update introduced a regression that could cause tar to fail to extract certain valid files. This update fixes the problem.

It was discovered that tar incorrectly handled certain crafted archive files. An attacker could possibly use this to inject hidden files with attacker-controlled content, bypassing pre-extraction inspection mechanisms.
