Ubuntu Security Notice 1168-1 - Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. Neil Horman discovered that NFSv4 did not correctly handle certain orders of operation with ACL data. A remote attacker with access to an NFSv4 mount could exploit this to crash the system, leading to a denial of service. Various other issues were also addressed.

linux vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

Multiple kernel flaws have been fixed.

Software Description:
- linux: Linux kernel

Details:

Timo Warns discovered that the LDM disk partition handling code did not
correctly handle certain values. By inserting a specially crafted disk
device, a local attacker could exploit this to gain root privileges.
(CVE-2011-1017)

Neil Horman discovered that NFSv4 did not correctly handle certain orders
of operation with ACL data. A remote attacker with access to an NFSv4 mount
could exploit this to crash the system, leading to a denial of service.
(CVE-2011-1090)

Timo Warns discovered that OSF partition parsing routines did not correctly
clear memory. A local attacker with physical access could plug in a
specially crafted block device to read kernel memory, leading to a loss of
privacy. (CVE-2011-1163)

Dan Rosenberg discovered that MPT devices did not correctly validate
certain values in ioctl calls. If these drivers were loaded, a local
attacker could exploit this to read arbitrary kernel memory, leading to a
loss of privacy. (CVE-2011-1494, CVE-2011-1495)

Tavis Ormandy discovered that the pidmap function did not correctly handle
large requests. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-1593)

Oliver Hartkopp and Dave Jones discovered that the CAN network driver did
not correctly validate certain socket structures. If this driver was
loaded, a local attacker could crash the system, leading to a denial of
service. (CVE-2011-1598, CVE-2011-1748)

Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl
values. A local attacker with access to the video subsystem could exploit
this to crash the system, leading to a denial of service, or possibly gain
root privileges. (CVE-2011-1745, CVE-2011-2022)

Vasiliy Kulikov discovered that the AGP driver did not check the size of
certain memory allocations. A local attacker with access to the video
subsystem could exploit this to run the system out of memory, leading to a
denial of service. (CVE-2011-1746, CVE-2011-1747)

Dan Rosenberg discovered that the DCCP stack did not correctly handle
certain packet structures. A remote attacker could exploit this to crash
the system, leading to a denial of service. (CVE-2011-1770)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
linux-image-2.6.32-33-386 2.6.32-33.70
linux-image-2.6.32-33-generic 2.6.32-33.70
linux-image-2.6.32-33-generic-pae 2.6.32-33.70
linux-image-2.6.32-33-ia64 2.6.32-33.70
linux-image-2.6.32-33-lpia 2.6.32-33.70
linux-image-2.6.32-33-powerpc 2.6.32-33.70
linux-image-2.6.32-33-powerpc-smp 2.6.32-33.70
linux-image-2.6.32-33-powerpc64-smp 2.6.32-33.70
linux-image-2.6.32-33-preempt 2.6.32-33.70
linux-image-2.6.32-33-server 2.6.32-33.70
linux-image-2.6.32-33-sparc64 2.6.32-33.70
linux-image-2.6.32-33-sparc64-smp 2.6.32-33.70
linux-image-2.6.32-33-versatile 2.6.32-33.70
linux-image-2.6.32-33-virtual 2.6.32-33.70

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
