Linux Kernel 2.6.16.9 memory corruption

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.

Summaryinfo

A vulnerability was found in Linux Kernel 2.6.16.9. It has been classified as problematic. Affected is an unknown function. Performing a manipulation results in memory corruption. This vulnerability is identified as CVE-2010-3301. Additionally, an exploit exists.

Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel 2.6.16.9 (Operating System). This affects an unknown code block. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The IA32 system call emulation functionality in arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.36-rc4-git2 on the x86_64 platform does not zero extend the %eax register after the 32-bit entry path to ptrace is used, which allows local users to gain privileges by triggering an out-of-bounds access to the system call table using the %rax register. NOTE: this vulnerability exists because of a CVE-2007-4573 regression.

The issue has been introduced in 03/20/2006. The weakness was released 09/22/2010 by Ben Hawkes (Website). The advisory is shared at sota.gen.nz. This vulnerability is uniquely identified as CVE-2010-3301. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed in ANSI C. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1647 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 49634 (CentOS 5 : kernel (CESA-2010:0704)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165607 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2010:041)).

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 Exploit-DB (15023), Tenable (49634), SecurityFocus (BID 43355†) and Vulnerability Center (SBV-27261†). Entries connected to this vulnerability are available at VDB-54842, VDB-54793, VDB-54791 and VDB-54643. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
