Fetchmail is a remote mail retrieval and forwarding utility.

|
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>

<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 ">=net-mail/fetchmail-6.3.14"</code>
|
|
</resolution>
