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

medium Nessus Plugin ID 72614

Language:

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.

Solution

Update the affected libtar and / or libtar-devel packages.
