Description:

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.

# emerge -pv ">=net-irc/bnc-2.8.9"
# emerge ">=net-irc/bnc-2.8.9"


Risk factor : Medium
