Description

This update fixes a local privilege escalation in udev.

  • udev did not check the origin of the netlink messages. A local attacker could fake device create events and so gain root privileges. (CVE-2009-1185)

The previous update did not apply the actual patch fixing this problem, as was reported to us by SGI.

Please reboot the machine after installing the update, or run: /etc/init.d/boot.udev restart
