Canonical Linux 11.04/11.10 input validation

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as critical has been found in Canonical Linux 11.04/11.10. This affects an unknown code. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The cupshelpers scripts in system-config-printer in Ubuntu 11.04 and 11.10, as used by the automatic printer driver download service, uses an "insecure connection" for queries to the OpenPrinting database, which allows remote attackers to execute arbitrary code via a man-in-the-middle (MITM) attack that modifies packages or repositories.

The weakness was presented 11/29/2011 by Marc Deslauriers (Website). The advisory is shared at xforce.iss.net. This vulnerability is uniquely identified as CVE-2011-4405. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 56868 (Ubuntu 11.04 / 11.10 : system-config-printer vulnerability (USN-1265-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 195212 (Ubuntu Security Notification for System-config-printer Vulnerability (USN-1265-1)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (71394), Tenable (56868), SecurityFocus (BID 50721†), OSVDB (77214†) and Vulnerability Center (SBV-33986†).
