NVD Description

Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path.
