A flaw was found in the way sudo handled its blacklist of environment variables. When the ‘env_reset’ option was disabled, a user permitted to run certain commands via sudo could use this flaw to run such a command with one of the blacklisted environment variables set, allowing them to run an arbitrary command with the target user’s privileges. (CVE-2014-0106)

Note: This issue does not affect the default configuration of the sudo package as shipped with Scientific Linux 5.
