<p>
Primoz Bratanic discovered that the sql_escape_func function of
FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also
discovered that FreeRADIUS fails to sanitize user-input before using it
in a SQL query, possibly allowing SQL command injection (BID 13540).
</p>
</description>
<impact type="normal">
<p>
By supplying carefully crafted input, a malicious user could cause an
SQL injection or a buffer overflow, possibly leading to the disclosure
and the modification of sensitive data or Denial of Service by crashing
the server.
</p>
</impact>
<workaround>
<p>
There are no known workarounds at this time.
</p>
</workaround>
<resolution>
<p>
All FreeRADIUS users should upgrade to the latest available version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-dialup/freeradius-1.0.2-r4&quot;</code>
</resolution>
