https://notcve.org/view.php?id=CVE-2023-48795
18 Dec 2023 — The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phas... • https://packetstorm.news/files/id/176280 • CWE-222: Truncation of Security-relevant Information CWE-354: Improper Validation of Integrity Check Value •

24 Sep 2023 — A vulnerability was found in OpenStack Barbican containers. This vulnerability is only applicable to deployments that utilize an all-in-one configuration. Barbican containers share the same CGROUP, USER, and NET namespace with the host system and other OpenStack services. If any service is compromised, it could gain access to the data transmitted to and from Barbican.

25 Jul 2023 — An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service.

10 Apr 2023 — A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.

01 Sep 2022 — A flaw was found in Keystone. There is a time lag (up to one hour in a default configuration) between when security policy says a token should be revoked from when it is actually revoked. This could allow a remote administrator to secretly maintain access for longer than expected. Se ha encontrado un fallo en Keystone.
