Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the udev package.

For the old stable distribution (etch), these problems have been fixed in version 0.105-4etch1.

For the stable distribution (lenny), these problems have been fixed in version 0.125-7+lenny1.
