========================================================================== Ubuntu Security Notice USN-3049-1 August 10, 2016
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:
Ben Hawkes discovered that the Linux netfilter implementation did not correctly perform validation when handling IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-3134)
Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress hugetlbfs support in X86 paravirtualized guests. An attacker in the guest OS could cause a denial of service (guest system crash). (CVE-2016-3961)
It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-4470)
Kangjie Lu discovered an information leak in the netlink implementation of the Linux kernel. A local attacker could use this to obtain sensitive information from kernel memory. (CVE-2016-5243)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.2.0-107-generic 3.2.0-107.148 linux-image-3.2.0-107-generic-pae 3.2.0-107.148 linux-image-3.2.0-107-highbank 3.2.0-107.148 linux-image-3.2.0-107-omap 3.2.0-107.148 linux-image-3.2.0-107-powerpc-smp 3.2.0-107.148 linux-image-3.2.0-107-powerpc64-smp 3.2.0-107.148 linux-image-3.2.0-107-virtual 3.2.0-107.148
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. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
