Linux Kernel 2.6.16.9 ivtvfb_ioctl information disclosure

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 was found in Linux Kernel 2.6.16.9 (Operating System). It has been declared as problematic. This vulnerability affects the function ivtvfb_ioctl. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. CVE summarizes:

The ivtvfb_ioctl function in drivers/media/video/ivtv/ivtvfb.c in the Linux kernel before 2.6.36-rc8 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an FBIOGET_VBLANK ioctl call.

The issue has been introduced in 03/20/2006. The weakness was shared 11/29/2010 by Dan Rosenberg as Bug 648666 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability was named CVE-2010-4079. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1592.

The vulnerability was handled as a non-public zero-day exploit for at least 1715 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 50825 (Debian DSA-2126-1 : linux-2.6 - privilege escalation/denial of service/information leak), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155446 (Oracle Enterprise Linux Update for Kernel (ELSA-2011-0007)).

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 Tenable (50825), SecurityFocus (BID 45062†) and Vulnerability Center (SBV-28475†). The entries VDB-55569, VDB-55563, VDB-55559 and VDB-55542 are related to this item. Once again VulDB remains the best source for vulnerability data.
