Linux Kernel 2.6.16.9 resource management

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.

A vulnerability classified as problematic was found in Linux Kernel 2.6.16.9 (Operating System). This vulnerability affects an unknown part. The manipulation with an unknown input leads to a resource management vulnerability. The CWE definition for the vulnerability is CWE-399. As an impact it is known to affect availability. CVE summarizes:

fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial of service (memory consumption) via a crafted exec system call, aka an "OOM dodging issue," a related issue to CVE-2010-3858.

The issue has been introduced in 03/20/2006. The weakness was released 01/22/2011 by Brad Spengler as Bug 625688 as confirmed bug report (Bugzilla). The advisory is available at bugzilla.redhat.com. This vulnerability was named CVE-2010-4243. The exploitation appears to be easy. Local access is required to approach this attack. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Roland McGrath in ANSI C and been published before and not just after the advisory. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1675 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 76634 (RHEL 6 : MRG (RHSA-2011:1253)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Red Hat 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)).

A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (64700), Tenable (76634) and Exploit-DB (15619). Entries connected to this vulnerability are available at 55675, 55566, 55562 and 55561.
