| Doc Text: |
A flaw was found in tar. An attacker can exploit this vulnerability by crafting a malicious tar archive containing a drive-relative symlink. This symlink, such as C:../../../target.txt, can trick the tar utility into writing files outside the intended extraction directory during normal archive extraction, leading to unauthorized file overwrite.
