    Package        : sudo
    CVE ID         : CVE-2014-9680
    Debian Bug     : 772707
    
    Jakub Wilk reported that sudo, a program designed to provide limited
    super user privileges to specific users, preserves the TZ variable from
    a user's environment without any sanitization. A user with sudo access
    may take advantage of this to exploit bugs in the C library functions
    which parse the TZ environment variable or to open files that the user
    would not otherwise be able to open. The later could potentially cause
    changes in system behavior when reading certain device special files or
    cause the program run via sudo to block.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.8.5p2-1+nmu2.
    
    We recommend that you upgrade your sudo packages.
