Several security issues were fixed in the kernel.
Salva Peiró discovered an information leak in the Linux kernel’s media- device driver. A local attacker could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2014-1739)
A bounds check error was discovered in the socket filter subsystem of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) via crafted BPF instructions. (CVE-2014-3144)
A remainder calculation error was discovered in the socket filter subsystem of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) via crafted BPF instructions. (CVE-2014-3145)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
