HID: LG: validate HID output report details
commit 0fb6bd06e06792469acc15bbe427361b56ada528 upstream.
A HID device could send a malicious output report that would cause the
lg, lg3, and lg4 HID drivers to write beyond the output report allocation
during an event, causing a heap overflow:
[ 325.245240] usb 1-1: New USB device found, idVendor=046d, idProduct=c287
...
[ 414.518960] BUG kmalloc-4096 (Not tainted): Redzone overwritten
Additionally, while lg2 did correctly validate the report details, it was
cleaned up and shortened.
CVE-2013-2893
