<p>libarchive is a library for manipulating different streaming archive
formats, including certain tar variants, several cpio formats, and both
BSD and GNU ar variants.
<p>Multiple vulnerabilities have been discovered in libarchive. Please
review the CVE identifiers referenced below for details.
<impact type="normal">
<p>A remote attacker could entice a user or automated process to open a
specially crafted archive using an application linked against libarchive,
possibly resulting in execution of arbitrary code with the privileges of
the process or a Denial of Service condition.
<p>There is no known workaround at this time.</p>
<p>All libarchive users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-arch/libarchive-3.1.2-r1"
<p>Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
