Ubuntu Security Notice 5879-1 - Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service or execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5878-1 - 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.

Ubuntu Security Notice 5877-1 - Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service or execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5874-1 - 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. It was discovered that a use-after-free vulnerability existed in the Bluetooth stack in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5876-1 - It was discovered that a memory leak existed in the Unix domain socket implementation of the Linux kernel. A local attacker could use this to cause a denial of service. 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.

Ubuntu Security Notice 5875-1 - It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

Debian Linux Security Advisory 5350-1 - Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code, information disclosure or spoofing.

Thistle's technology will give device makers a way to easily integrate features for secure updates, memory management, and communications into their products, Snyder says.

### Impact A bug was found in containerd where supplementary groups are not set up properly inside a container. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. Downstream applications that use the containerd client library may be affected as well. ### Patches This bug has been fixed in containerd v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue. Users who rely on a downstream application that uses containerd's client library should check that application for a separate advisory and instructions. ### Workarounds Ensure that the `"USER $USERNAME"` Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to `ENTRYPOINT ["su", "-",...
