DESCRIPTION

* CVE-2014-3611: Denial-of-service in KVM emulated programmable interval timer.

Incorrect locking in the KVM emulated programmable interval timer (PIT)
could crash the host kernel under specific conditions. A local attacker
could use this flaw to cause a denial-of-service in the host KVM.


* CVE-2014-3535: NULL pointer dereference in VxLAN packet logging.

A NULL pointer dereference flaw was found in the way the Linux kernel's
networking implementation handled logging while processing certain invalid
packets coming in via a VxLAN interface. A remote attacker could use this
flaw to crash the system by sending a specially crafted packet to such an
interface.


* CVE-2014-3184: Invalid memory write in HID drivers.

Several HID drivers (Cherry Cymotion keyboard, KYE/Genius devices,
Logitech devices, Monterey Genius KB29E keyboard, Petalynx Maxtor
remote control, and Sunplus wireless desktop) are vulnerable to an
out-of-bounds write due to some off-by-one bugs.  This could occur if
a HID device report offers an invalid report descriptor size.

A local user with physical access to the system could use this flaw to
write past an allocated memory buffer.


* CVE-2014-3185: Memory corruption in USB serial WhiteHEAD device driver.

The USB ConnectTech WhiteHEAT serial driver is vulnerable to a memory
corruption flaw. It could occur when reading completion commands via USB
Request Blocks buffers.

A local user with physical access to the system could use this flaw to
corrupt kernel memory area or crash the system kernel resulting in a
denial-of-service.
