Ubuntu Security Notice 2146-1 - Sebastien Macke discovered that Sudo incorrectly handled blacklisted environment variables when the env_reset option was disabled. A local attacker could use this issue to possibly run unintended commands by using blacklisted environment variables. In a default Ubuntu installation, the env_reset option is enabled by default. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. It was discovered that the Sudo init script set a date in the past on existing timestamp files instead of using epoch to invalidate them completely. A local attacker could possibly modify the system time to attempt to reuse timestamp files. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 12.10 and Ubuntu 13.10. Various other issues were also addressed.

Red Hat Security Advisory 2014-0266-01 - The sudo utility allows system administrators to give certain users the ability to run commands as root. 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. Note: This issue does not affect the default configuration of the sudo package as shipped with Red Hat Enterprise Linux 5.
