+ <title>GnuTLS: Multiple vulnerabilities</title>
+ <synopsis>
+ Multiple vulnerabilities in GnuTLS might result in a Denial of Service,
+ spoofing or the generation of invalid keys.

+ </affected>
+ <background>
+ <p>
+ GnuTLS is an Open Source implementation of the TLS 1.0 and SSL 3.0
+ protocols.
+ </p>
+ </background>
+ <description>
+ <p>
+ The following vulnerabilities were found in GnuTLS:
+ </p>
+ <ul>
+ <li>Miroslav Kratochvil reported that lib/pk-libgcrypt.c does not
+ properly handle corrupt DSA signatures, possibly leading to a
+ double-free vulnerability (CVE-2009-1415).</li>
+ <li>Simon Josefsson
+ reported that GnuTLS generates RSA keys stored in DSA structures when
+ creating a DSA key (CVE-2009-1416).</li>
+ <li>Romain Francoise reported
+ that the _gnutls_x509_verify_certificate() function in
+ lib/x509/verify.c does not perform time checks, resulting in the
+ "gnutls-cli" program accepting X.509 certificates with validity times
+ in the past or future (CVE-2009-1417).</li>
+ </ul>
+ </description>
+ <impact type="normal">
+ <p>
+ A remote attacker could entice a user or automated system to process a
+ specially crafted DSA certificate, possibly resulting in a Denial of
+ Service condition. NOTE: This issue might have other unspecified impact
+ including the execution of arbitrary code. Furthermore, a remote
+ attacker could spoof signatures on certificates and the "gnutls-cli"
+ application can be tricked into accepting an invalid certificate.
+ </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-2.6.6"</code>
+ </resolution>
