Description Vasyl Kaigorodov 2014-06-12 12:33:39 UTC 
Security researcher Looben Yang reported a buffer overflow in Gamepad API when it is exercised with a gamepad device with non-contiguous axes. This can be either an actual physical device or by the installation of a virtual gamepad. This results in a potentially exploitable crash. The Gamepad API was introduced in Firefox 29 and this issue does not affect earlier versions.
