<description>
|
|
<p>
|
|
A flaw exists in the input parsing of BNC where part of the
|
|
sbuf_getmsg() function handles the backspace character incorrectly.

|
|
<impact type="normal">
|
|
<p>
|
|
A remote user could issue commands using fake authentication
|
|
credentials and possibly gain access to scripts running on the client
|
|
side.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All BNC users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=net-irc/bnc-2.8.9"
|
|
# emerge ">=net-irc/bnc-2.8.9"</code>
