17 Aug 2022 — An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service.

15 Jul 2021 — An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

28 May 2021 — A flaw was found in openstack-neutron's default Open vSwitch firewall rules. By sending carefully crafted packets, anyone in control of a server instance connected to the virtual switch can impersonate the IPv6 addresses of other systems on the network, resulting in denial of service or in some cases possibly interception of traffic intended for other destinations. Only deployments using the Open vSwitch driver are affected. Source: OpenStack project.

02 Sep 2020 — A flaw was found in the Ansible Engine, in ansible-engine 2.8.x before 2.8.15 and ansible-engine 2.9.x before 2.9.13, when installing packages using the dnf module. GPG signatures are ignored during installation even when disable_gpg_check is set to False, which is the default behavior.

27 Nov 2017 — When libvirtd is configured by OSP director (tripleo-heat-templates) to use the TLS transport it defaults to the same certificate authority as all non-libvirtd services. As no additional authentication is configured this allows these services to connect to libvirtd (which is equivalent to root access). If a vulnerability exists in another service it could, combined with this flaw, be exploited to escalate privileges to gain control over compute nodes.
