NVD Description

Note: Versions mentioned in the description apply only to the upstream perl package and not the perl package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name.
