Linux Kernel up to 2.6.38.8 rose_parse_ccitt 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 was found in Linux Kernel up to 2.6.38.8 (Operating System). It has been rated as critical. This issue affects the function rose_parse_ccitt. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability. The summary by CVE is:

The rose_parse_ccitt function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 does not validate the FAC_CCITT_DEST_NSAP and FAC_CCITT_SRC_NSAP fields, which allows remote attackers to (1) cause a denial of service (integer underflow, heap memory corruption, and panic) via a small length value in data sent to a ROSE socket, or (2) conduct stack-based buffer overflow attacks via a large length value in data sent to a ROSE socket.

The issue has been introduced in 03/14/2011. The weakness was presented 06/21/2012 (Website). The advisory is shared at github.com. The identification of this vulnerability is CVE-2011-4913 since 12/23/2011. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 465 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 55104 (Ubuntu 10.04 LTS : linux, linux-ec2 vulnerabilities (USN-1141-1)), 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 167785 (SUSE Enterprise Linux Security update for Linux Kernel (SUSE-SU-2015:0812-1)).

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 Tenable (55104) and Vulnerability Center (SBV-44337†). See VDB-4416, VDB-4544, VDB-61074 and VDB-61071 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
