A vulnerability has been discovered in KVIrc, allowing for the remote execution of arbitrary code.
|Package||net-irc/kvirc on all architectures|
|Affected versions||< 3.2.6_pre20070714|
|Unaffected versions||>= 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"
