GNU tar is a program for creating and manipulating tar files.
GNU tar was found to contain a path traversal flaw. If a malicious user could get a user to use a tar archive, it is possible that arbitrary files that the user has write permissions to could be overwritten. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-4131 to this issue.

use of
physical security, firewalls, ACLs, VPNs, and other generally-accepted
networking practices until such time as an update becomes available and
can
be installed.
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
