VAR-202103-0218
Vulnerability from variot - Updated: 2025-12-22 22:59A 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. Canonical Ubuntu is a set of desktop application-based GNU/Linux operating system developed by British company Canonical. A security vulnerability exists in the Ubuntu lldp software that could be exploited by an attacker to trigger a denial of service attack. The following products and models are affected: Ubuntu 20.10 openvswitch-common, Ubuntu 20.04 LTS openvswitch-common Ubuntu 18.04 LTS openvswitch-common, Ubuntu 16.04 LTS: openvswitch-common.
For the stable distribution (buster), these problems have been fixed in version 2.10.6+ds1-0+deb10u1.
For the detailed security status of openvswitch please refer to its security tracker page at: https://security-tracker.debian.org/tracker/openvswitch

Summary:
An update for imgbased, redhat-release-virtualization-host and redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 8.
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:
RHEL 8-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64 Red Hat Virtualization 4 Hypervisor for RHEL 8 - noarch
- Description:
The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.
The ovirt-node-ng packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines.

"data": "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. Canonical Ubuntu is a set of desktop application-based GNU/Linux operating system developed by British company Canonical. A security vulnerability exists in the Ubuntu lldp software that could be exploited by an attacker to trigger a denial of service attack. The following products and models are affected: Ubuntu 20.10 openvswitch-common, Ubuntu 20.04 LTS openvswitch-common Ubuntu 18.04 LTS openvswitch-common, Ubuntu 16.04 LTS: openvswitch-common. \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 2.10.6+ds1-0+deb10u1. \n\nFor the detailed security status of openvswitch please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/openvswitch\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nDFZQX3XNSM1Gi0xHlV6uYQgi2HRuPk5QdW2TqmEN7XUNeQ9xdpI=\n=BZCg\n-----END PGP SIGNATURE-----\n. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nGentoo Linux Security Advisory GLSA 202311-16\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n https://security.gentoo.org/\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\n Severity: Low\n Title: Open vSwitch: Multiple Vulnerabilities\n Date: November 26, 2023\n Bugs: #765346, #769995, #803107, #887561\n ID: 202311-16\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nSynopsis\n=======\nMultiple denial of service vulnerabilites have been found in Open\nvSwitch. \n\nBackground\n=========\nOpen vSwitch is a production quality multilayer virtual switch. \n\nAffected packages\n================\nPackage Vulnerable Unaffected\n-------------------- ------------ ------------\nnet-misc/openvswitch \u003c 2.17.6 \u003e= 2.17.6\n\nDescription\n==========\nMultiple vulnerabilities have been discovered in Open vSwitch.
