+Package        : linux-2.6
+Vulnerability  : several vulnerabilities
+Problem type   : local
+Debian-specific: no
+CVE Id(s)      : CVE-2007-6694 CVE-2008-0007 CVE-2008-1294 CVE-2008-1375
+
+Several local 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-2007-6694
+
+    Cyrill Gorcunov reported a NULL pointer dereference in code specific
+    to the CHRP PowerPC platforms. Local users could exploit this issue
+    to achieve a Denial of Service (DoS).
+
+CVE-2008-0007
+
+    Nick Piggin of SuSE discovered a number of issues in subsystems which
+    register a fault handler for memory mapped areas. This issue can be
+    exploited by local users to achieve a Denial of Service (DoS) and possibly
+    execute arbitrary code.
+
+CVE-2008-1294
+
+    David Peer discovered that users could escape administrator imposed cpu
+    time limitations (RLIMIT_CPU) by setting a limit of 0.
+
+CVE-2008-1375
+
+    Alexander Viro discovered a race condition in the directory notification
+    subsystem that may allow local users to cause a Denial of Service (oops)
+    condition.
+
+For the stable distribution (etch), this problem has been fixed in version
+2.6.18.dfsg.1-18etch3.
+
+The unstable (sid) and testing distributions will be fixed soon.
+
+We recommend that you upgrade your linux-2.6, fai-kernels, and
+user-mode-linux packages.
+
+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
+
+The following matrix lists additional source packages that were rebuilt for
+compatability with or to take advantage of this update:
+
+                                             Debian 4.0 (etch)
+     fai-kernels                             1.17+etch.18etch3
+     user-mode-linux                         2.6.18-1um-2etch.18etch3
+
+You may use an automated update by adding the resources from the
+footer to the proper configuration.

+Debian GNU/Linux 4.0 alias etch
+-------------------------------
+
+Stable updates are available for alpha, amd64, arm, hppa, i386, ia64,
+mips, mipsel, powerpc, sparc and s390.
+
+
+  These files will probably be moved into the stable distribution on
+  its next update.
