CVE-2009-4031 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Linux kernel vulnerabilities
Amerigo Wang and Eric Sesterhenn discovered that the HFS and ext4
filesystems did not correctly check certain disk structures. If a user
were tricked into mounting a specially crafted filesystem, a remote
attacker could crash the system or gain root privileges. (CVE-2009-4020,
CVE-2009-4308)
It was discovered that FUSE did not correctly check certain requests.
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
affected. (CVE-2009-4021)
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 o
