sudo before 1.6.8p2 allows local users to execute arbitrary commands by using "()" style environment variables to create functions that have the same name as any program within the bash script that is called without using the program's full pathname.

These programs have multiple vulnerabilities that could allow a remote attacker to execute arbitrary code.

Liam Helmer noticed that sudo, a program that provides limited super user privileges to specific users, does not clean the environment sufficiently. Bash functions and the CDPATH variable are still passed through to the program running as privileged user, leaving possibilities to overload system routines. These vulnerabilities can only be exploited by users who have been granted limited super user privileges.

Liam Helmer discovered a flow in sudo's environment sanitizing. This flaw could allow a malicious users with permission to run a shell script that uses the bash shell to run arbitrary commands.

The problem is fixed in sudo 1.6.8p2; the provided packages have been patched to correct the issue.
