Updated libtar packages fixes security vulnerability

Two heap-based buffer overflow flaws were found in the way libtar handled certain archives. If a user were tricked into expanding a specially-crafted archive, it could cause the libtar executable or an application using libtar to crash or, potentially, execute arbitrary code (CVE-2013-4397).
