Ubuntu

USN-3107-2: Linux kernel (Raspberry Pi 2) vulnerability

Ubuntu Security Notice USN-3107-2

24th October, 2016

linux-raspi2 vulnerability

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

  • Ubuntu 16.10

Summary

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

Software description

  • linux-raspi2
    – Linux kernel for Raspberry Pi 2

Details

It was discovered that a race condition existed in the memory manager of
the Linux kernel when handling copy-on-write breakage of private read-only
memory mappings. A local attacker could use this to gain administrative
privileges.

Update instructions

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

Ubuntu 16.10:
linux-image-4.8.0-1017-raspi2

4.8.0-1017.20

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.
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.

DSA-3701 nginx – security update

Dawid Golunski reported the nginx web server packages in Debian
suffered from a privilege escalation vulnerability (www-data to root)
due to the way log files are handled. This security update changes
ownership of the /var/log/nginx directory root. In addition,
/var/log/nginx has to be made accessible to local users, and local
users may be able to read the log files themselves local until the
next logrotate invocation.
