GNU tar is the standard GNU utility for creating and manipulating
tar archives, a common format used for creating backups and
distributing files on UNIX-like systems.
Jim Meyering discovered a flaw in the handling of certain header
fields that could result in a buffer overflow when extracting or
listing the contents of an archive.
<impact type="normal">
A remote attacker could construct a malicious tar archive that
could potentially execute arbitrary code with the privileges of the
user running GNU tar.
There is no known workaround at this time.
All GNU tar users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-arch/tar-1.15.1-r1&quot;</code>
