Background
system-config-printer is a package used in Ubuntu 11.04 and 11.10 for managing printers. It includes the cupshelpers scripts, which are responsible for the automatic printer driver download service. This service queries the OpenPrinting database to download printer drivers. However, the cupshelpers scripts use an insecure connection for these queries, making them vulnerable to man-in-the-middle (MITM) attacks.
Vulnerability Detail
The vulnerability (CVE-2011-4405) allows remote attackers to execute arbitrary code by modifying packages or repositories during the insecure queries to the OpenPrinting database. This means that an attacker could intercept the queries and inject malicious code, potentially leading to the execution of arbitrary commands on the affected system.

FAQ
system-config-printer is a package used in Ubuntu 11.04 and 11.10 for managing printers. It includes the cupshelpers scripts, which are responsible for the automatic printer driver download service.
The OpenPrinting database is a repository of printer drivers that can be automatically downloaded by system-config-printer. It is used to provide driver compatibility for various printer models.
A man-in-the-middle attack is a type of cyber attack where an attacker intercepts communication between two parties without their knowledge. In this case, the attacker can modify the packages or repositories during the insecure queries to the OpenPrinting database.
By modifying the packages or repositories during the insecure queries, an attacker can inject malicious code. This code can potentially lead to the execution of arbitrary commands on the affected system, giving the attacker unauthorized access and control.
To protect your system, it is recommended to update the system-config-printer package to version 1.3.7-1 or later. This will ensure that the insecure connection is replaced with a secure one when querying the OpenPrinting database.
