spice-gtk is a set of GObject and Gtk objects for connecting to Spice servers and a client GUI.
A vulnerability was found in spice-gtk client due to the incorrect use of integer types and missing overflow checks.
An attacker, by enticing the user to join a malicious server, could remotely execute arbitrary code or cause a Denial of Service condition.
There is no known workaround at this time.
All spice-gtk users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/spice-gtk-0.34"
