  tag_insight = "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. (CVE-2014-0106)

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. (LP: #1223297)";
