Calendar Grey July 29, 2013
Scroller Ubuntu
Debian 9.0 encounters package flaws that necessitate timely upgrades to bolster protection and avert potential breaches.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-ec2: Linux kernel for EC2

Details:

Jonathan Salwan discovered an information leak in the Linux kernel's cdrom

driver. A local user can exploit this leak to obtain sensitive information

from kernel memory if the CD-ROM drive is malfunctioning. (CVE-2013-2164)

A flaw was discovered in the Linux kernel when an IPv6 socket is used to

connect to an IPv4 destination. An unprivileged local user could exploit

this flaw to cause a denial of service (system crash). (CVE-2013-2232)

An information leak was discovered in the IPSec key_socket implementation

in the Linux kernel. An local user could exploit this flaw to examine

potentially sensitive information in kernel memory. (CVE-2013-2234)

An information leak was discovered in the Linux kernel's IPSec key_socket

when using the notify_policy interface. A local user could exploit this

flaw to examine potentially sensitive information in k...

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-355-ec2      2.6.32-355.68

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.
