A flaw was found in sudoedit. A race condition vulnerability and improper symbolic link resolution could be used by a local unprivileged user to test for the existence of directories and files not normally accessible to the user. This flaw cannot be used to read the content or write to arbitrary files on the file system. The highest threat from this vulnerability is to data confidentiality.
Mitigation
Enabling the symbolic link protection (/proc/sys/fs/protected_symlinks set to 1) is sufficient to mitigate this flaw.
