Descriptions
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.
sudo en versiones anteriores a 1.8.12 no garantiza que la variable de entorno TZ esté asociada con un archivo zoneinfo, lo que permite a usuarios locales abrir archivos arbitrarios para acceso de lectura (pero no ver el contenido del archivo) ejecutando un programa dentro de una sesión sudo, como lo demuestra interfiriendo con la salida del terminal, descartando los mensajes del kernel-log o reposicionando las unidades de cinta.
It was discovered that sudo did not perform any checks of the TZ environment variable value. If sudo was configured to preserve the TZ environment variable, a local user with privileges to execute commands via sudo could possibly use this flaw to achieve system state changes not permitted by the configured commands.
Note: The default sudoers configuration in Red Hat Enterprise Linux removes the TZ variable from the environment in which commands run by sudo are executed.
