Linux Kernel 2.6.16.9 ax25_getname 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) and classified as problematic. Affected by this issue is the function ax25_getname. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

The ax25_getname function in net/ax25/af_ax25.c in the Linux kernel before 2.6.37-rc2 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure.

The issue has been introduced in 03/20/2006. The weakness was disclosed 01/03/2011 as Bug 649713 as not defined bug report (Bugzilla). The advisory is available at bugzilla.redhat.com. This vulnerability is handled as CVE-2010-3875. Local access is required to approach this attack. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 1750 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 55028 (Debian DSA-2240-1 : 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 165554 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2011:012)).

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 (62982), Tenable (55028), SecurityFocus (BID 44630†) and Vulnerability Center (SBV-29116†).
