Subject: [USN-758-1] udev vulnerabilities

===========================================================
Ubuntu Security Notice USN-758-1             April 15, 2009
udev vulnerabilities
CVE-2009-1185, CVE-2009-1186
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.10
Ubuntu 8.04 LTS
Ubuntu 8.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  udev                            079-0ubuntu35.1

Ubuntu 7.10:
  udev                            113-0ubuntu17.2

Ubuntu 8.04 LTS:
  udev                            117-8ubuntu0.2

Ubuntu 8.10:
  udev                            124-9ubuntu0.2

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.

Details follow:

Sebastian Krahmer discovered that udev did not correctly validate netlink
message senders.  A local attacker could send specially crafted messages
to udev in order to gain root privileges. (CVE-2009-1185)

Sebastian Krahmer discovered a buffer overflow in the path encoding routines
in udev.  A local attacker could exploit this to crash udev, leading to a
denial of service. (CVE-2009-1186)
