[v2.7] kernel: ttusb-dec: buffer overflow in ioctl (CVE-2014-8884)
Stack-based buffer overflow in the ttusbdecfe_dvbs_diseqc_send_master_cmd function in drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel before 3.17.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via a large message length in an ioctl call.
Fixed in 3.10.61 and 3.14.25.
