    Published: 16 Apr 2010Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
