Summary

openvswitch security update

Details

Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license.

Security Fix(es):

A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2020-35498)

A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2020-27827)

Buffer overflow in the lldp_decode function in daemon/protocols/lldp.c in lldpd before 0.8.0 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries.(CVE-2015-8011)

Severity

9.8 (Critical)

Detection rules are retrieved from Rulezet.

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.
