+ <title>GnuTLS: Execution of arbitrary code</title>
+ <synopsis>
+ Multiple vulnerabilities might allow for the execution of arbitrary code in
+ daemons using GnuTLS.

+ <p>
+ GnuTLS is an implementation of Secure Sockets Layer (SSL) 3.0 and
+ Transport Layer Security (TLS) 1.0, 1.1 and 1.2.

+ <description>
+ <p>
+ Ossi Herrala and Jukka Taimisto of Codenomicon reported three
+ vulnerabilities in libgnutls of GnuTLS:
+ </p>
+ <ul>
+ <li>
+ "Client Hello" messages containing an invalid server name can lead to a
+ buffer overflow when evaluating "Security Parameters" (CVE-2008-1948).
+ </li>
+ <li>
+ Multiple "Client Hello" messages can lead to a NULL pointer dereference
+ (CVE-2008-1949).
+ </li>
+ <li>
+ A TLS handshake including an encrypted "Client Hello" message and an
+ invalid record length could lead to a buffer overread (CVE-2008-1950).
+ </li>
+ </ul>
+ </description>
+ <impact type="high">
+ <p>
+ Unauthenticated remote attackers could exploit these vulnerabilities to
+ cause Denial of Service conditions in daemons using GnuTLS. The first
+ vulnerability (CVE-2008-1948) might allow for the execution of
+ arbitrary code with the privileges of the daemon handling incoming TLS
+ connections.
+ </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-2.2.5"</code>
