Multiple race condition vulnerabilities have been discovered in nano. For further information please consult the CVE entries referenced below.

Under certain conditions, a local, user-assisted attacker could possibly overwrite arbitrary files via a symlink attack on an attacker-owned file that is being edited by the victim, or change the ownership of arbitrary files.

There is no known workaround at this time.
