KVIrc: Remote arbitrary code execution A vulnerability has been discovered in KVIrc, allowing for the remote execution of arbitrary code. kvirc 2007-09-13 2007-09-13 183174 remote 3.2.6_pre20070714 3.2.6_pre20070714

KVIrc is a free portable IRC client based on Qt.

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.

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.

There is no known workaround at this time.

All KVIrc users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-irc/kvirc-3.2.6_pre20070714"
