Title: BNC: Input validation flaw (GLSA 200410-13)
Date: October 15, 2004
Updated: May 22, 2006
BNC contains an input validation flaw which might allow a remote attacker to issue arbitrary IRC related commands.
BNC is an IRC proxying server
Vulnerable: < 2.8.9
Unaffected: >= 2.8.9
Architectures: All supported architectures
A flaw exists in the input parsing of BNC where part of the sbuf_getmsg() function handles the backspace character incorrectly.
A remote user could issue commands using fake authentication credentials and possibly gain access to scripts running on the client side.
There is no known workaround at this time.
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"
