Red Hat Product Errata RHSA-2013:1418 0 normal SHIPPED_LIVE Moderate: libtar security update 2013-10-10 20:39:19 UTC

Description Murray McAllister 2013-10-02 08:40:45 UTC 
Two heap-based buffer overflow flaws were found in the way libtar handled archives that use the GNU longname and longlink extensions. 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.
