Package : unzip
Vulnerability : directory traversal
Problem-Type : local
Debian-specific: no
CVE Ids : CAN-2003-0282

A directory traversal vulnerability in UnZip 5.50 allows attackers to
bypass a check for relative pathnames ("../") by placing certain invalid
characters between the two "." characters.

We recommend that you update your unzip package.
