+Vulnerability  : several
+Problem-Type   : local/remote
+Debian-specific: no
+CVE ID         : CVE-2007-1496 CVE-2007-1497 CVE-2007-1861
+
+Several local and remote vulnerabilities have been discovered in the Linux
+kernel that may lead to a denial of service or the execution of arbitrary
+code. The Common Vulnerabilities and Exposures project identifies the
+following problems:
+
+CVE-2007-1496
+
+    Michal Miroslaw reported a DoS vulnerability (crash) in netfilter.
+    A remote attacker can cause a NULL pointer dereference in the
+    nfnetlink_log function.
+
+
+CVE-2007-1497
+
+    Patrick McHardy reported an vulnerability in netfilter that may
+    allow attackers to bypass certain firewall rules. The nfctinfo
+    value of reassembled IPv6 packet fragments were incorrectly initalized
+    to 0 which allowed these packets to become tracked as ESTABLISHED.
+
+CVE-2007-1861
+
+    Jaco Kroon reported a bug in which NETLINK_FIB_LOOKUP packages were
+    incorrectly routed back to the kernel resulting in an infinite
+    recursion condition. Local users can exploit this behavior
+    to cause a DoS (crash).
+
+This problem has been fixed in the stable distribution in version 
+2.6.18.dfsg.1-12etch2.
+
+The following matrix lists additional packages that were rebuilt for
+compatibility with or to take advantage of this update:
+
+                                 Debian 4.0 (etch)
+     fai-kernels                 1.17+etch2
+     user-mode-linux             2.6.18-1um-2etch2
+
+We recommend that you upgrade your kernel package immediately and reboot
+the machine. If you have built a custom kernel from the kernel source
+package, you will need to rebuild to take advantage of these fixes.
+
+Upgrade Instructions
+--------------------
+
+wget url
+        will fetch the file for you
+dpkg -i file.deb
+        will install the referenced file.
+
+If you are using the apt-get package manager, use the line for
+sources.list as given below:
+
+apt-get update
+        will update the internal database
+apt-get upgrade
+        will install corrected packages
+
+You may use an automated update by adding the resources from the
+footer to the proper configuration.
+
+
+Debian GNU/Linux 4.0 alias etch
+--------------------------------
+
+
+  These files will probably be moved into the stable distribution on
+  its next update.
