## Description

Sudo 1.6.9 before 1.8.5, when env\_reset is disabled, does not properly
check environment variables for the env\_delete restriction, which allows
local users with sudo permissions to bypass intended command restrictions
via a crafted environment variable.

## Notes

---

### [jdstrand](https://launchpad.net/~jdstrand)

Ubuntu uses env\_reset by default

---

### [mdeslaur](https://launchpad.net/~mdeslaur)

low priority since this is only vulnerable in a non-default
configuration, and not using env\_reset is insecure anyway.
