Detail

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:

A flaw was discovered in the user space memory copying for the pipe iovecs in the Linux kernel. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges. (CVE-2015-1805)

Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter JIT optimization. A local attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2015-4700)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-88-generic 3.2.0-88.126
linux-image-3.2.0-88-generic-pae 3.2.0-88.126
linux-image-3.2.0-88-highbank 3.2.0-88.126
linux-image-3.2.0-88-omap 3.2.0-88.126
linux-image-3.2.0-88-powerpc-smp 3.2.0-88.126
linux-image-3.2.0-88-powerpc64-smp 3.2.0-88.126
linux-image-3.2.0-88-virtual 3.2.0-88.126

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.
