autofs vulnerability

Releases

• Ubuntu 14.10

Packages

• 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.
