Ubuntu Security Notice 6628-2 - Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service.

Ubuntu Security Notice 6636-1 - It was discovered that ClamAV incorrectly handled parsing certain OLE2 files. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service. Amit Schendel discovered that the ClamAV ClamD service incorrectly handled the VirusEvent feature. An attacker able to connect to ClamD could possibly use this issue to execute arbitrary code.

Ubuntu Security Notice 6635-1 - It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service. Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker could use this to cause a denial of service or possibly expose sensitive information.

Red Hat Security Advisory 2024-0827-03 - An update for.NET 8.0 is now available for Red Hat Enterprise Linux 8. Issues addressed include a denial of service vulnerability.

Red Hat Security Advisory 2024-0820-03 - Red Hat Advanced Cluster Management for Kubernetes 2.8.5 General Availability release images, which provide security updates and fix bugs. Issues addressed include denial of service and traversal vulnerabilities.
