Vulnerability from variot - Updated: 2024-07-23 20:17In Open vSwitch (OvS) 2.7.0, while parsing an OFPT_QUEUE_GET_CONFIG_REPLY type OFP 1.0 message, there is a buffer over-read that is caused by an unsigned integer underflow in the function ofputil_pull_queue_get_config_reply10 in lib/ofp-util.c. Open vSwitch (OvS) Contains an integer underflow vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. Open vSwitch (OVS) is a multi-layer virtual switch product based on open source technology (following the Apache2.0 license). It supports large-scale network automation, standard management interfaces and protocols, etc. through programming extensions. There is an integer overflow vulnerability in the 'ofputil_pull_queue_get_config_reply10' function of lib/ofp-util.c file in OvS 2.7.0 version.

===================================================================== Red Hat Security Advisory
Synopsis: Moderate: openvswitch security, bug fix, and enhancement update Advisory ID: RHSA-2017:2418-01 Product: Fast Datapath Advisory URL: https://access.redhat.com/errata/RHSA-2017:2418 Issue date: 2017-08-03 CVE Names: CVE-2017-9214 CVE-2017-9263 CVE-2017-9264 CVE-2017-9265 =====================================================================
- Summary:
An update for openvswitch is now available for Fast Datapath for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
- Relevant releases/architectures:
Channel to provide early releases to layered products - noarch, x86_64
- Description:
Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic.
The following packages have been upgraded to a later upstream version: openvswitch (2.7.2). An attacker could use this flaw to cause a remote DoS. (CVE-2017-9214)
-
In Open vSwitch (OvS), while parsing an OpenFlow role status message there is a call to the abort() function for undefined role status reasons in the function
ofp_print_role_status_messageinlib/ofp-print.cthat may be leveraged toward a remote DoS attack by a malicious switch. (CVE-2017-9263) -
A buffer over-read was found in the Open vSwitch (OvS) firewall implementation. This flaw can be triggered by parsing a specially crafted TCP, UDP, or IPv6 packet. A remote attack could use this flaw to cause a Denial of Service (DoS). An attacker could use this flaw to cause a Denial of Service (DoS). (CVE-2017-9265)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
