========================================================================== Ubuntu Security Notice USN-1912-1 July 29, 2013
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
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 kernel memory. (CVE-2013-2237)
Kees Cook discovered a format string vulnerability in the Linux kernel's disk block layer. A local user with administrator privileges could exploit this flaw to gain kernel privileges. (CVE-2013-2851)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 10.04 LTS: linux-image-2.6.32-50-386 2.6.32-50.112 linux-image-2.6.32-50-generic 2.6.32-50.112 linux-image-2.6.32-50-generic-pae 2.6.32-50.112 linux-image-2.6.32-50-ia64 2.6.32-50.112 linux-image-2.6.32-50-lpia 2.6.32-50.112 linux-image-2.6.32-50-powerpc 2.6.32-50.112 linux-image-2.6.32-50-powerpc-smp 2.6.32-50.112 linux-image-2.6.32-50-powerpc64-smp 2.6.32-50.112 linux-image-2.6.32-50-preempt 2.6.32-50.112 linux-image-2.6.32-50-server 2.6.32-50.112 linux-image-2.6.32-50-sparc64 2.6.32-50.112 linux-image-2.6.32-50-sparc64-smp 2.6.32-50.112 linux-image-2.6.32-50-versatile 2.6.32-50.112 linux-image-2.6.32-50-virtual 2.6.32-50.112
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.
