Mandriva Linux Security Advisory : libtar (MDVSA-2014:045)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

A directory traversal attack was reported against libtar, a C library
for manipulating tar archives. The application does not validate the
filenames inside the tar archive, allowing to extract files in
arbitrary path. An attacker can craft a tar file to override files
beyond the tar_extract_glob and tar_extract_all prefix parameter
(CVE-2013-4420).

The updated packages have been patched to correct this issue.
