<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).

<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 ">=net-libs/gnutls-2.12.18"
