+ performing Base64 encoding.

+ <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 "&gt;=dev-libs/cyrus-sasl-2.1.23"</code>
