RHSA-2009:0427 -- udev security update (Important)

oval:org.mitre.oval:def:28703

Updated udev packages that fix one security issue are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. udev provides a user-space API and implements a dynamic device directory providing only the devices present on the system. udev replaces devfs in order to provide greater hot plug functionality. Netlink is a datagram oriented service used to transfer information between kernel modules and user-space processes. It was discovered that udev did not properly check the origin of Netlink messages. A local attacker could use this flaw to gain root privileges via a crafted Netlink message sent to udev causing it to create a world-writable block device file for an existing system block device (for example the root file system).
