+ <p>
+ Fetchmail is a remote mail retrieval and forwarding utility.
+ </p>
+ </background>
+ <description>
+ <p>
+ Multiple vulnerabilities have been reported in Fetchmail:
+ </p>
+ <ul>
+ <li>The sdump() function might trigger a heap-based buffer overflow
+ during the escaping of non-printable characters with the high bit set
+ from an X.509 certificate (CVE-2010-0562).</li>
+ <li>The vendor reported
+ that Fetchmail does not properly handle Common Name (CN) fields in
+ X.509 certificates that contain an ASCII NUL character. Specifically,
+ the processing of such fields is stopped at the first occurrence of a
+ NUL character. This type of vulnerability was recently discovered by
+ Dan Kaminsky and Moxie Marlinspike (CVE-2009-2666).</li>
+ </ul>
+ </description>
+ <impact type="normal">
+ <p>
+ A remote attacker could entice a user to connect with Fetchmail to a
+ specially crafted SSL-enabled server in verbose mode, possibly
+ resulting in the execution of arbitrary code with the privileges of the
+ user running the application. NOTE: The issue is only existent on
+ platforms on which char is signed.
+ </p>
+ <p>
+ Furthermore, a remote attacker might employ a specially crafted X.509
+ certificate, containing a NUL character in the Common Name field to
+ conduct man-in-the-middle attacks on SSL connections made using
+ Fetchmail.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Fetchmail users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-mail/fetchmail-6.3.14"</code>
+ </resolution>
