Executive Summary

This vulnerability is a double free issue in the jarun nnn software up to version 5.1, specifically in the function show_content_in_floating_window/run_cmd_as_plugin within the file nnn/src/nnn.c. A double free occurs when the software attempts to free the same memory space twice, which can lead to undefined behavior or potential exploitation. The attack requires local access to the system.

Impact Analysis

The vulnerability can lead to a denial of service or potentially allow an attacker with local access to cause instability or crash the application by exploiting the double free condition. However, it does not impact confidentiality or integrity, only availability.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to install the patch identified by commit 2f07ccdf21e705377862e5f9dfa31e1694979ac7 that addresses the double free issue in the show_content_in_floating_window/run_cmd_as_plugin function of nnn. Since the attack requires local access, ensure that only trusted users have local access until the patch is applied.
