    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.

    Vulnerability  : missing input sanitising
    Problem-Type   : local

    Debian Bug     : 281665
    
    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.
    
    For the stable distribution (woody) these problems have been fixed in
    version 1.6.6-1.2.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 1.6.8p3.
    
    We recommend that you upgrade your sudo package.
