CVE-2010-1160

Description

GNU nano before 2.2.4 does not verify whether a file has been changed before it is overwritten in a file-save operation, which allows local user-assisted attackers to overwrite arbitrary files via a symlink attack on an attacker-owned file that is being edited by the victim.
