| Doc Text: |
A flaw was found in the gpgtar utility in GnuPG. When extracting an archive into a directory containing pre-existing symbolic links (symlinks), the tool can follow those links instead of staying within the target directory. An attacker can provide a crafted archive that, when extracted by an unsuspecting user, creates or overwrites files outside the intended destination directory. Any unauthorized file writes are limited to the filesystem permissions of the user performing the extraction.
