Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
Input: focaltech - fix array out-of-bounds in focaltech_process_rel_packet<br />
<br />
Make finger2 (and also finger1) unsigned, so that if the finger index in<br />
the packet is 0 then subtracting 1 creates an array index which overflows<br />
above the existing check for FOC_MAX_FINGERS, as the existing comment says<br />
it should, instead of writing to state->fingers[-1].
