+Debian Bug : 633738
+
+Several vulnerabilities have been discovered in the Linux kernel that may lead
+to a privilege escalation, denial of service or information leak. The Common
+Vulnerabilities and Exposures project identifies the following problems:
+
+[*]CVE-2009-4067
+
+ Rafael Dominguez Vega of MWR InfoSecurity reported an issue in auerswald
+ module, a driver for Auerswald PBX/System Telephone USB devices.
+ Attackers with physical access to a system's USB ports could obtain
+ elevated privileges using a specially crafted USB device.
+
+[*]CVE-2011-0712
+
+ Rafael Dominguez Vega of MWR InfoSecurity reported an issue in the caiaq
+ module, a USB driver for Native Instruments USB audio devices. Attackers
+ with physical access to a system's USB ports could obtain elevated
+ privileges using a specially crafted USB device.
+
+CVE-2011-1020
+
+ Kees Cook discovered an issue in the /proc filesystem that allows local
+ users to gain access to sensitive process information after execution of a
+ setuid binary.
+
+[*]CVE-2011-2209
+
+ Dan Rosenberg discovered an issue in the osf_sysinfo() system call on
+ the alpha architecture. Local users could obtain access to sensitive
+ kernel memory.
+
+[*]CVE-2011-2211
+
+ Dan Rosenberg discovered an issue in the osf_wait4() system call on the
+ alpha architecture permitting local users to gain elevated privileges.
+
+[*]CVE-2011-2213
+
+ Dan Rosenberg discovered an issue in the INET socket monitoring interface.
+ Local users could cause a denial of service by injecting code and causing
+ the kernel to execute an infinite loop.
+
+CVE-2011-2484
+
+ Vasiliy Kulikov of Openwall discovered that the number of exit handlers that
+ a process can register is not capped, resulting in local denial of service
+ through resource exhaustion (cpu time and memory).
+
+CVE-2011-2491
+
+ Vasily Averin discovered an issue with the NFS locking implementation. A
+ malicious NFS server can cause a client to hang indefinitely in an unlock
+ call.
+
+CVE-2011-2492
+
+ Marek Kroemeke and Filip Palian discovered that uninitialized struct
+ elements in the Bluetooth subsystem could lead to a leak of sensitive kernel
+ memory through leaked stack memory.
+
+CVE-2011-2495
+
+ Vasiliy Kulikov of Openwall discovered that the io file of a process' proc
+ directory was world-readable, resulting in local information disclosure of
+ information such as password lengths.
+
+CVE-2011-2496
+
+ Robert Swiecki discovered that mremap() could be abused for local denial of
+ service by triggering a BUG_ON assert.
+
+CVE-2011-2497
+
+ Dan Rosenberg discovered an integer underflow in the Bluetooth subsystem,
+ which could lead to denial of service or privilege escalation.
+
+CVE-2011-2525
+
+ Ben Pfaff reported an issue in the network scheduling code. A local user
+ could cause a denial of service (NULL pointer dereference) by sending a
+ specially crafted netlink message.
+
+CVE-2011-2928
+
+ Timo Warns discovered that insufficient validation of Be filesystem images
+ could lead to local denial of service if a malformed filesystem image is
+ mounted.
+
+CVE-2011-3188
+
+ Dan Kaminsky reported a weakness of the sequence number generation in the
+ TCP protocol implementation. This can be used by remote attackers to inject
+ packets into an active session.
+
+CVE-2011-3191
+
+ Darren Lavender reported an issue in the Common Internet File System (CIFS).
+ A malicious file server could cause memory corruption leading to a denial of
+ service.
+
+This update also includes a fix for a regression introduced with the previous
+security fix for CVE-2011-1768 (Debian: #633738)
+
+For the oldstable distribution (lenny), this problem has been fixed in
+version 2.6.26-26lenny4.
+
+The following matrix lists additional source packages that were rebuilt for
+compatibility with or to take advantage of this update:
+
+ Debian 5.0 (lenny)
+ user-mode-linux 2.6.26-1um-2+26lenny4
+
+We recommend that you upgrade your linux-2.6 and user-mode-linux packages.
+These updates will not become active until after your system is rebooted.
+
+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.
+
+Further information about Debian Security Advisories, how to apply
+these updates to your system and frequently asked questions can be
