tar and unzip are programs widely used for distribution of multiple files concatenated (commonly known as an archive).
Both tar and unzip have directory transversal vulnerabilities in the way they extract filenames containning .. or / characteres at the beginning.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2001-1267, CVE-2001-1268, CVE-2001-1269 and CVE-2002-0399 to this issue.
