Details

A flaw was found in nano. In environments with permissive umask settings, a local attacker can exploit incorrect directory permissions (0777 instead of 0700) for the ~/.local directory. This allows the attacker to inject a malicious .desktop launcher, which could lead to unintended actions or information disclosure if the launcher is subsequently processed.
