Ubuntu Security Notice 5854-1 - It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with Enhanced Indirect Branch Restricted Speculation did not properly handle RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive information.

Ubuntu Security Notice 5850-1 - It was discovered that the Bluetooth HCI implementation in the Linux kernel did not properly deallocate memory in some situations. An attacker could possibly use this cause a denial of service. It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform bounds checking in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service or possibly execute arbitrary code.

Single sign-on and request smuggling to the fore in another stellar year for web security research

In the cloud-first world, the security goal is to ensure only qualified users can access information across clouds.

Five months after AWS customers were alerted about three vulnerabilities, nearly none had plugged the holes. The reasons why underline a need for change.

OpenSearch Anomaly Detection identifies atypical data and receives automatic notifications. There is an issue with the application of document and field level restrictions in the Anomaly Detection plugin, where users with the Anomaly Detector role can read aggregated numerical data (e.g. averages, sums) of fields that are otherwise restricted to them. This issue only affects authenticated users who were previously granted read access to the indexes containing the restricted fields. This issue has been patched in versions 1.3.8 and 2.6.0. There are no known workarounds for this issue.

The greatly expanding attack surface created by the cloud needs to be protected.
