Synopsis
=======
BNC contains an input validation flaw which might allow a remote attacker to issue arbitrary IRC related commands.
Background
=========
BNC is an IRC proxying server
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-irc/bnc < 2.8.9 >= 2.8.9
Description
==========
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.
Resolution
