<p>Libksba is a X.509 and CMS (PKCS#7) library.</p>
<p>libksba is vulnerable to two integer overflows and a Denial of Service
vulnerability. Please read the references for additional details.
<impact type="normal">
<p>Remote attackers could cause Denial of Service or unspecified other
vectors through various integer overflows.
<p>There is no known workaround at this time.</p>
<p>All libksba users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=dev-libs/libksba-1.3.3"
