Date: September 13, 2007
Bugs: #183174

Synopsis
========
A vulnerability has been discovered in KVIrc, allowing for the remote
execution of arbitrary code.
Background
==========
KVIrc is a free portable IRC client based on Qt.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-irc/kvirc < 3.2.6_pre20070714 >= 3.2.6_pre20070714
Description
===========
Stefan Cornelius from Secunia Research discovered that the
"parseIrcUrl()" function in file src/kvirc/kernel/kvi_ircurl.cpp does
not properly sanitise parts of the URI when building the command for
KVIrc's internal script system.
Impact
======
A remote attacker could entice a user to open a specially crafted
irc:// URI, possibly leading to the remote execution of arbitrary code
with the privileges of the user running KVIrc. Successful exploitation
requires that KVIrc is registered as the default handler for irc:// or
similar URIs.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All KVIrc users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/kvirc-3.2.6_pre20070714"
