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.
