Published: 01 October 2018

Nullsoft Scriptable Install System (NSIS) before 2.49 uses temporary folder locations that allow unprivileged local users to overwrite files. This allows a local attack in which either a plugin or the uninstaller can be replaced by a Trojan horse program.

From the Ubuntu security team

It was discovered that NSIS incorrectly handled temporary folders. An attacker could possibly use this issue to execute arbitrary commands.
