Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10

Summary:

The system could be made to run programs as an administrator.

Software Description: - linux-raspi2: Linux kernel for Raspberry Pi 2

Details:

Nathan Williams discovered that overlayfs in the Linux kernel incorrectly handled setattr operations. A local unprivileged attacker could use this to create files with administrative permission attributes and execute arbitrary code with elevated privileges.

Update instructions:

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

Ubuntu 15.10:
linux-image-4.2.0-1018-raspi2 4.2.0-1018.25

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.
