+
+Several vulnerabilities have been discovered in the Linux kernel that
+may lead to a denial of service or privilege escalation. The Common
+Vulnerabilities and Exposures project identifies the following
+problems:
+
+CVE-2008-4307
+
+ Bryn M. Reeves reported a denial of service in the NFS filesystem.
+ Local users can trigger a kernel BUG() due to a race condition in
+ the do_setlk function.
+
+CVE-2008-5395
+
+ Helge Deller discovered a denial of service condition that allows
+ local users on PA-RISC systems to crash a system by attempting to
+ unwind a stack contiaining userspace addresses.
+
+CVE-2008-5701
+
+ Vlad Malov reported an issue on 64-bit MIPS systems where a local
+ user could cause a system crash by crafing a malicious binary
+ which makes o32 syscalls with a number less than 4000.
+
+CVE-2008-5702
+
+ Zvonimir Rakamaric reported an off-by-one error in the ib700wdt
+ watchdog driver which allows local users to cause a buffer
+ underflow by making a specially crafted WDIOC_SETTIMEOUT ioctl
+ call.
+
+CVE-2008-5713
+
+ Flavio Leitner discovered that a local user can cause a denial
+ of service by generating large amounts of traffic on a large SMP
+ system, resulting in soft lockups.
+
+CVE-2009-0028
+
+ Chris Evans discovered a situation in which a child process can
+ send an arbitrary signal to its parent.
+
+CVE-2009-0029
+
+ Christian Borntraeger discovered an issue effecting the alpha,
+ mips, powerpc, s390 and sparc64 architectures that allows local
+ users to cause a denial of service or potentially gain elevated
+ privileges.
+
+CVE-2009-0031
+
+ Vegard Nossum discovered a memory leak in the keyctl subsystem
+ that allows local users to cause a denial of service by consuming
+ all of kernel memory.
+
+CVE-2009-0065
+
+ Wei Yongjun discovered a memory overflow in the SCTP
+ implementation that can be triggered by remote users, permitting
+ remote code execution.
+
+CVE-2009-0322
+
+ Pavel Roskin provided a fix for an issue in the dell_rbu driver
+ that allows a local user to cause a denial of service (oops) by
+ reading 0 byts from a sysfs entry.
+
+CVE-2009-0675
+
+ Roel Kluin discovered inverted logic in the skfddi driver that
+ permits local, unprivileged users to reset the driver statistics.
+
+CVE-2009-0676
+
+ Clement LECIGNE discovered a bug in the sock_getsockopt function
+ that may result in leaking sensitive kernel memory.
+
+CVE-2009-0834
+
+ Roland McGrath discovered an issue on amd64 kernels that allows
+ local users to circumvent system call audit configurations which
+ filter based on the syscall numbers or argument details.
+
+CVE-2009-0859
+
+ Jiri Olsa discovered that a local user can cause a denial of
+ service (system hang) using a SHM_INFO shmctl call on kernels
+ compiled with CONFIG_SHMEM disabled. This issue does not affect
+ prebuilt Debian kernels.
+
+CVE-2009-1192
+
+ Shaohua Li reported an issue in the AGP subsystem they may allow
+ local users to read sensitive kernel memory due to a leak of
+ uninitialized memory.
+
+CVE-2009-1265
+
+ Thomas Pollet reported an overflow in the af_rose implementation
+ that allows remote attackers to retrieve uninitialized kernel
+ memory that may contain sensitive data.
+
+CVE-2009-1336
+
+ Trond Myklebust reported an issue in the encode_lookup() function in
+ the nfs server subsystem that allows local users to cause a denial
+ of service (oops in encode_lookup()) by use of a long filename.
+
+CVE-2009-1337
+
+ Oleg Nesterov discovered an issue in the exit_notify function that
+ allows local users to send an arbitrary signal to a process by
+ running a program that modifies the exit_signal field and then
+ uses an exec system call to launch a setuid application.
+
+CVE-2009-1439
+
+ Pavan Naregundi reported an issue in the CIFS filesystem code that
+ allows remote users to overwrite memory via a long
+ nativeFileSystem field in a Tree Connect response during mount.
+
+For the oldstable distribution (etch), this problem has been fixed in
+version 2.6.18.dfsg.1-24etch2.
+
+We recommend that you upgrade your linux-2.6, fai-kernels, and
+user-mode-linux packages.
+
+Note: Debian carefully tracks all known security issues across every
+linux kernel package in all releases under active security support.
+However, given the high frequency at which low-severity
+security issues are discovered in the kernel and the resource
+requirements of doing an update, updates for lower priority issues
+will normally not be released for all kernels at the same time. Rather,
+they will be released in a staggered or "leap-frog" fashion.
+
+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.24etch2
+ user-mode-linux 2.6.18-1um-2etch.24etch2
+
+You may use an automated update by adding the resources from the
+footer to the proper configuration.
+
+Debian GNU/Linux 4.0 alias etch
+-------------------------------
+
+Oldstable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
+
+[FILL IN]
+
+ These changes will probably be included in the oldstable distribution on
+ its next update.
