- tar - GNU tar archive utility
Details
USN-8477-1 fixed a vulnerability in tar. That fix was incomplete and could
cause tar to fail to extract old archives that recorded a nonzero size for
directory entries, resulting in a regression.
This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
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.
