========================================================================== Ubuntu Security Notice USN-2133-1 March 07, 2014
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
Mathy Vanhoef discovered an error in the the way the ath9k driver was handling the BSSID masking. A remote attacker could exploit this error to discover the original MAC address after a spoofing atack. (CVE-2013-4579)
Andrew Honig reported an error in the Linux Kernel's Kernel Virtual Machine (KVM) VAPIC synchronization operation. A local user could exploit this flaw to gain privileges or cause a denial of service (system crash). (CVE-2013-6368)
halfdog reported an error in the AMD K7 and K8 platform support in the Linux kernel. An unprivileged local user could exploit this flaw on AMD based systems to cause a denial of service (task kill) or possibly gain privileges via a crafted application. (CVE-2014-1438)
An information leak was discovered in the Linux kernel's hamradio YAM driver for AX.25 packet radio. A local user with the CAP_NET_ADMIN capability could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2014-1446)
Matthew Thode reported a denial of service vulnerability in the Linux kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN capability (and the SELinux mac_admin permission if running in enforcing mode) could exploit this flaw to cause a denial of service (kernel crash). (CVE-2014-1874)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.2.0-60-generic 3.2.0-60.91 linux-image-3.2.0-60-generic-pae 3.2.0-60.91 linux-image-3.2.0-60-highbank 3.2.0-60.91 linux-image-3.2.0-60-omap 3.2.0-60.91 linux-image-3.2.0-60-powerpc-smp 3.2.0-60.91 linux-image-3.2.0-60-powerpc64-smp 3.2.0-60.91 linux-image-3.2.0-60-virtual 3.2.0-60.91
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.
