+                 CVE-2007-4308
+                 
+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-2007-2172
+
+    Thomas Graf reported a typo in the IPV4 protocol handler that could
+    be used by a local attacker to overrun an array via crafted packets,
+    potentially resulting in a Denial of Service (system crash).
+    The DECnet counterpart of this issue was already fixed in DSA-1356.
+
+CVE-2007-2875
+
+    iDefense reported a potential integer underflow in the cpuset filesystem
+    which may permit local attackers to gain access to sensitive kernel
+    memory. This vulnerability is only exploitable if the cpuset filesystem
+    is mounted.
+
+CVE-2007-3105
+
+    The PaX Team discovered a potential buffer overflow in the random number
+    generator which may permit local users to cause a denial of service or
+    gain additional privileges. This issue is not believed to effect default
+    Debian installations where only root has sufficient privileges to exploit
+    it.
+
+CVE-2007-3843
+
+    A coding error in the CIFS subsystem permits the use of unsigned messages
+    even if the client has been configured the system to enforce
+    signing by passing the sec=ntlmv2i mount option. This may allow remote
+    attackers to spoof CIFS network traffic.
+
+CVE-2007-4308
+
+    Alan Cox reported an issue in the aacraid driver that allows unprivileged
+    local users to make ioctl calls which should be restricted to admin
+    privileges.
+
+These problems have been fixed in the stable distribution in version 
+2.6.18.dfsg.1-13etch2.
+
+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+etch5
+     user-mode-linux             2.6.18-1um-2etch4
+
+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.
