<impact type="normal">
<p>A physically proximate attacker could possibly execute arbitrary code
using a specially crafted smart card.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All OpenSC users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/opensc-0.11.13-r2"
</code>
<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.
