<impact type="high">
<p>
A remote unauthenticated user might send specially crafted packets to a
daemon using Cyrus-SASL, possibly resulting in the execution of
arbitrary code with the privileges of the user running the daemon or a
Denial of Service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Cyrus-SASL users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/cyrus-sasl-2.1.23&quot;</code>
