<description>
|
|
<p>
|
|
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">
|
|
<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.

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

|
</p>
|

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Cyrus-SASL users should upgrade to the latest version:

|

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/cyrus-sasl-2.1.23"</code>
