Description

Perl Archive::Tar module is prone to a directory-traversal vulnerability because it fails to validate user-supplied data.

A successful attack can allow the attacker to overwrite files on a computer in the context of the user running the affected application. Successful exploits may aid in further attacks.

Note that all applications using Perl Archive::Tar module may be affected.
