<p>libotr is a portable off-the-record messaging library.</p>
<p>Multiple heap-based buffer overflows are present in the Base64 decoder
of libotr.

in arbitrary code execution with the privileges of the process or a
Denial of Service condition.
<p>There is no known workaround at this time.</p>
<p>All libotr users should upgrade to the latest version:</p>
