QSN-4058-1: bash vulnerability

July 15, 2019


A system hardening measure could be bypassed.


It was discovered that Bash incorrectly handled the restricted shell. An attacker could possibly use this issue to escape restrictions and execute any command.



A general update will usually fix all issues, but to make sure, you can check your current version with:

$ dpkg -l bash

If the current version you have is before 4.3-14ubuntu1.4, run the following:

$ sudo apt-get update
$ sudo apt-get install bash
