Intel E1000 up to 7.4.35 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.

A vulnerability was found in Intel E1000 and classified as critical. This issue affects an unknown function. 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:

drivers/net/r8169.c in the r8169 driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to (1) cause a denial of service (temporary network outage) via a packet with a crafted size, in conjunction with certain packets containing A characters and certain packets containing E characters; or (2) cause a denial of service (system crash) via a packet with a crafted size, in conjunction with certain packets containing \0 characters, related to the value of the status register and erroneous behavior associated with the RxMaxSize register. NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1389.

The weakness was published 01/12/2010 by Fabian Yamaguchi (Website). The advisory is shared at rhn.redhat.com. The identification of this vulnerability is CVE-2009-4537 since 12/31/2009. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 08/30/2021).

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 46725 (Debian DSA-2053-1 : 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 165591 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2010:023)).

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 (55647), Tenable (46725), SecurityFocus (BID 37521†), Secunia (SA38031†) and SecurityTracker (ID 1023419†). Similar entries are available at VDB-40214, VDB-51918, VDB-51836 and VDB-51835.
