QEMU e1000e NIC Emulation 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, which was classified as problematic, was found in QEMU (Virtualization Software) (affected version unknown). This affects an unknown functionality of the component e1000e NIC Emulation. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as 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. This is going to have an impact on availability. The summary by CVE is:

QEMU (aka Quick Emulator), when built with the e1000e NIC emulation support, allows local guest OS privileged users to cause a denial of service (infinite loop) via vectors related to setting the initial receive / transmit descriptor head (TDH/RDH) outside the allocated descriptor buffer.

The bug was discovered 05/19/2017. The weakness was disclosed 06/08/2017 by Li Qiang with Qihoo 360 (oss-sec). The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2017-9310 since 05/30/2017. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 18 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 100630 (GLSA-201706-03 : QEMU: Multiple vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 276796 (Fedora Security Update for qemu (FEDORA-2017-f941184db1)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.qemu.org. 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 Tenable (100630) and SecurityFocus (BID 98766†). The entries VDB-101891 and VDB-102118 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
