Sebastian Kramer discovered two vulnerabilities in udev, the /dev and hotplug management daemon.

  • CVE-2009-1185 udev does not check the origin of NETLINK messages, allowing local users to gain root privileges.

  • CVE-2009-1186 udev suffers from a buffer overflow condition in path encoding, potentially allowing arbitrary code execution.
