CVE-2014-3185 on Ubuntu 12.04 LTS (precise) - medium.
Description:
Multiple buffer overflows in the command_port_read_callback function in drivers/usb/serial/whiteheat.c in the Whiteheat USB Serial Driver in the Linux kernel before 3.16.2 allow physically proximate attackers to execute arbitrary code or cause a denial of service (memory corruption and system crash) via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with a bulk response. Several bounds check flaws allowing for buffer overflows were discovered in the Linux kernel's Whiteheat USB serial driver. A physically proximate attacker could exploit these flaws to cause a denial of service (system crash) via a specially crafted device.
