Ubuntu Security Notice 6444-1 - Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6439-1 - It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.

A threat actor, presumably from Tunisia, has been linked to a new campaign targeting exposed Jupyter Notebooks in a two-fold attempt to illicitly mine cryptocurrency and breach cloud environments. Dubbed Qubitstrike by Cado, the intrusion set utilizes Telegram API to exfiltrate cloud service provider credentials following a successful compromise. "The payloads for the Qubitstrike campaign are

If not correctly locked down, Jupyter Notebook offers a novel initial access vector that hackers can use to compromise enterprise cloud environments, as seen in a recent hacking incident.

### Impact There is an issue with the implementation of tenant permissions in OpenSearch Dashboards where authenticated users with read-only access to a tenant can perform create, edit and delete operations on index metadata of dashboards and visualizations in that tenant, potentially rendering them unavailable. This issue does not affect index data, only metadata. Dashboards correctly enforces read-only permissions when indexing and updating documents. This issue does not provide additional read access to data users don’t already have. ### Mitigation This issue can be mitigated by disabling the tenants functionality for the cluster. Versions 1.3.14 and 2.11.0 contain a fix for this issue. ### For more information If you have any questions or comments about this advisory, please contact AWS/Amazon Security via our issue reporting page (https://aws.amazon.com/security/vulnerability-reporting/) or directly via email to [[email protected]](mailto:[email protected]).

### Impact An issue has been identified with how OpenSearch handled incoming requests on the HTTP layer. An unauthenticated user could force an OpenSearch node to exit with an OutOfMemory error by sending a moderate number of malformed HTTP requests. The issue was identified by Elastic Engineering and corresponds to security advisory [ESA-2023-13](https://discuss.elastic.co/t/elasticsearch-8-9-0-7-17-13-security-update/343616) (CVE-2023-31418). ### Mitigation Versions 1.3.14 and 2.11.0 contain a fix for this issue. ### For more information If you have any questions or comments about this advisory, please contact AWS/Amazon Security via our issue reporting page (https://aws.amazon.com/security/vulnerability-reporting/) or directly via email to [[email protected]](mailto:[email protected]). Please do not create a public GitHub issue.
