Comment 1 Nicolas Salguero 2024-06-13 14:07:20 CEST 
Suggested advisory:
========================

The updated package fixes a security vulnerability:

A vulnerability was found in GNU Nano that allows a possible privilege escalation through an insecure temporary file. If Nano is killed while editing, a file it saves to an emergency file with the permissions of the running user provides a window of opportunity for attackers to escalate privileges through a malicious symlink. (CVE-2024-5742)

MGA9-64 Plasma Wayland on HP-Pavillion
No installation issues.
Tried to use it, found it even clumsier than vi. Anyway, did some operations on a text file, found rather accidentally that mouse operation could be set-reset.
Probably due to this being a slow machine, closing nano left the mouse cursor with the icon to resize a window wherever I moved it. After a while, it returned to normal operation.
In view of other tests above, good to go.
