USN-6021-1: Chromium vulnerabilities It was discovered that Chromium did not properly manage memory in several components. A remote attacker could possibly use this issue to corrupt memory via a crafted HTML page, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-1528, CVE-2023-1530, CVE-2023-1531, CVE-2023-1533, CVE-2023-1811, CVE-2023-1815, CVE-2023-1818) It was discovered that Chromium could be made to access memory out of bounds in WebHID. A remote attacker could possibly use this issue to corrupt memory via a malicious HID device, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-1529) It was discovered that Chromium could be made to access memory out of bounds in several components. A remote attacker could possibly use this issue to corrupt memory via a crafted HTML page, resulting in a denial of service, or possibly execute arbitrary code.

USN-6020-1: Linux kernel (BlueField) vulnerabilities It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3669) It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. (CVE-2022-2196) Gerald Lee discovered that the USB Gadget file system implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-4382) It was discovered that the RNDIS [ more… ]

USN-6018-1: Apport vulnerability Chen Lu, Lei Wang, and YiQi Sun discovered a privilege escalation vulnerability in apport-cli when viewing crash reports and unprivileged users are allowed to run sudo less. A local attacker on a specially configured system could use this to escalate their privilege. Source: USN-6018-1: Apport vulnerability
