code in applications or daemons that authenticate using SASL.

Cyrus-SASL is an implementation of the Simple Authentication and
Security Layer.
James Ralston reported that in certain situations, Cyrus-SASL does not
properly terminate strings which can result in buffer overflows when
performing Base64 encoding.
<impact type="high">
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.
There is no known workaround at this time.
All Cyrus-SASL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/cyrus-sasl-2.1.23&quot;</code>
