USN-2579-1: autofs vulnerability
27 April 2015
autofs could be made to run programs as an administrator if program maps were configured.
- autofs - kernel-based automounter for Linux
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
