Ubuntu 14.10 : autofs vulnerability (USN-2579-1)

Medium Nessus Plugin ID 83111


The remote Ubuntu host is missing a security-related patch.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected autofs package.
