Vulnerability details
The vulnerability allows a local authenticated user to gain access to sensitive information.
sudo before 1.8.12 does not ensure that the TZ environment variable is associated with a zoneinfo file, which allows local users to open arbitrary files for read access (but not view file contents) by running a program within an sudo session, as demonstrated by interfering with terminal output, discarding kernel-log messages, or repositioning tape drives.
