Scroller Ubuntu
Critical security flaws addressed in the Linux kernel for Ubuntu 10.04 LTS; ensure to refresh with updated packages for optimal system protection.
Multiple kernel flaws have been fixed.

Summary

Multiple kernel flaws have been fixed.

Software Description:

- linux-fsl-imx51: Linux kernel for IMX51

Details:

Dan Rosenberg discovered that the Linux kernel TIPC implementation

contained multiple integer signedness errors. A local attacker could

exploit this to gain root privileges. (CVE-2010-3859)

Dan Rosenberg discovered that multiple terminal ioctls did not correctly

initialize structure memory. A local attacker could exploit this to read

portions of kernel stack memory, leading to a loss of privacy.

(CVE-2010-4075, CVE-2010-4076, CVE-2010-4077)

Dan Rosenberg discovered that the socket filters did not correctly

initialize structure memory. A local attacker could create malicious

filters to read portions of kernel stack memory, leading to a loss of

privacy. (CVE-2010-4158)

Dan Rosenberg discovered that the Linux kernel L2TP implementation

contained multiple integer signedness errors. A local attacker could

exploit this to to crash the kernel, or possibly gain root privile...

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.31-610-imx51    2.6.31-610.28

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.
