Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS : nano vulnerability (USN-7064-1)

medium Nessus Plugin ID 209028

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-7064-1 advisory.

 It was discovered that nano allowed a possible privilege escalation through an insecure temporary file. If nano was killed while editing, the permissions granted to the emergency save file could be used by an attacker to escalate privileges using a malicious symlink.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected nano and / or nano-tiny packages.
