 desc = 'The remote host is affected by the vulnerability described in GLSA-200410-13
(BNC: Input validation flaw)


    A flaw exists in the input parsing of BNC where part of the sbuf_getmsg()
    function handles the backspace character incorrectly.
  
Impact

    A remote user could issue commands using fake authentication credentials
    and possibly gain access to scripts running on the client side.
  
Workaround

    There is no known workaround at this time.
  
References:
    http://www.gotbnc.com/changes.html#2.8.9


Solution: 
    All BNC users should upgrade to the latest version:
    # emerge sync
    # emerge -pv ">=net-irc/bnc-2.8.9"
    # emerge ">=net-irc/bnc-2.8.9"
  

Risk factor : Medium
