A local attacker with access to FUSE mounts could exploit this to
crash the system or possibly gain root privileges. Ubuntu 9.10 was not
It was discovered that KVM did not correctly decode certain guest
instructions. A local attacker in a guest could exploit this to
trigger high scheduling latency in the host, leading to a denial of
service. Ubuntu 6.06 was not affected. (CVE-2009-4031)
It was discovered that the OHCI fireware driver did not correctly
handle certain ioctls. A local attacker could exploit this to crash
the system, or possibly gain root privileges. Ubuntu 6.06 was not

Florian Westphal discovered that bridging netfilter rules could be
modified by unprivileged users. A local attacker could disrupt network
traffic, leading to a denial of service. (CVE-2010-0007)
