Scientific Linux Security Update : udev on SL5.x i386/x86_64

high Nessus Plugin ID 60570

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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). (CVE-2009-1185)

After installing the update, the udevd daemon will be restarted automatically.

Solution

Update the affected libvolume_id, libvolume_id-devel and / or udev packages.
