Debian DSA-1772-1 : udev - several vulnerabilities

high Nessus Plugin ID 36172
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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.


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.
