Ubuntu Security Notice USN-2579-1
April 27, 2015

autofs vulnerability
==========================================================================

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

- Ubuntu 14.10

Summary:

autofs could be made to run programs as an administrator if program maps
were configured.

Software Description:
- autofs: kernel-based automounter for Linux

Details:

It was discovered that autofs incorrectly filtered environment variables
when using program maps. When program maps were configured, a local user
could use this issue to escalate privileges.

This update changes the default behaviour by adding a prefix to environment
variables. Sites using program maps will need to adapt to the new variable
names, or revert to the previous names by using a new configuration option
called FORCE_STANDARD_PROGRAM_MAP_ENV.

Update instructions:

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

Ubuntu 14.10:
autofs 5.0.8-1ubuntu1.1

After a standard system update you need to reboot your computer to make
all the necessary changes.
