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