Ubuntu 10.10 USN-1159-1 Critical: Kernel Flaws and Denial of Service

Calendar Grey July 13, 2011
Scroller Ubuntu
Various vulnerabilities in the kernel impacting Ubuntu 10.10 have been addressed. It's recommended to update your system immediately to improve security.
Multiple kernel flaws have been fixed.

Summary

Multiple kernel flaws have been fixed.

Software Description:

- linux-mvl-dove: Linux kernel for DOVE

Details:

Brad Spengler discovered that the kernel did not correctly account for

userspace memory allocations during exec() calls. A local attacker could

exploit this to consume all system memory, leading to a denial of service.

(CVE-2010-4243)

Alexander Duyck discovered that the Intel Gigabit Ethernet driver did not

correctly handle certain configurations. If such a device was configured

without VLANs, a remote attacker could crash the system, leading to a

denial of service. (CVE-2010-4263)

Nelson Elhage discovered that Econet did not correctly handle AUN packets

over UDP. A local attacker could send specially crafted traffic to crash

the system, leading to a denial of service. (CVE-2010-4342)

Dan Rosenberg discovered that IRDA did not correctly check the size of

buffers. On non-x86 systems, a local attacker could exploit this to read

kernel heap memory...

Update Instructions

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

Ubuntu 10.10:
  linux-image-2.6.32-417-dove     2.6.32-417.34

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.
