IcedTea-Web Plugin applet buffer overflow
|icedtea-applet-bo (79894)||High Risk|
The IcedTea-Web Plugin is vulnerable to a heap-based buffer overflow, caused by an error related to the triggering of an applet where specific events are attached. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Apply the appropriate update for your system. See References.
