+ <background>
+ <p>GnuTLS is an Open Source implementation of the TLS 1.2 and SSL 3.0
+ protocols.
+ </p>
+ </background>
+ <description>
+ <p>Multiple vulnerabilities have been found in GnuTLS:</p>
+
+ <ul>
+ <li>An error in libgnutls does not properly sanitize "\0" characters from
+ certificate fields (CVE-2009-2730).
+ </li>
+ <li>An error in the TLS and SSL protocols mistreats renegotiation
+ handshakes (CVE-2009-3555).
+ </li>
+ <li>A boundary error in the "gnutls_session_get_data()" function in
+ gnutls_session.c could cause a buffer overflow (CVE-2011-4128).
+ </li>
+ <li>An error in the "_gnutls_ciphertext2compressed()" function in
+ gnutls_cipher.c could cause memory corruption (CVE-2012-1573).
+ </li>
+ </ul>
+ </description>
+ <impact type="normal">
+ <p>A remote attacker could perform man-in-the-middle attacks to spoof
+ arbitrary SSL servers or cause a Denial of Service condition in
+ applications linked against GnuTLS.
+ </p>
+ </impact>
+ <workaround>
+ <p>There is no known workaround at this time.</p>
+ </workaround>
+ <resolution>
+ <p>All GnuTLS users should upgrade to the latest version:</p>
+
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-libs/gnutls-2.12.18"
+ </code>
