Ubuntu Security Notice 5605-1 - Asaf Modelevsky discovered that the Intel 10GbE PCI Express Ethernet driver for the Linux kernel performed insufficient control flow management. A local attacker could possibly use this to cause a denial of service. It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Sagemath version 9.0 suffers from overflow and denial of service vulnerabilities.

Ubuntu Security Notice 5602-1 - Asaf Modelevsky discovered that the Intel 10GbE PCI Express Ethernet driver for the Linux kernel performed insufficient control flow management. A local attacker could possibly use this to cause a denial of service. It was discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a race condition with a resultant use-after-free.

UBports Ubuntu Touch 16.04 allows the screen-unlock passcode to be used for a privileged shell via Sudo. This passcode is only four digits, far below typical length/complexity for a user account's password.

Ubuntu Security Notice 4976-2 - USN-4976-1 fixed a vulnerability in Dnsmasq. This update provides the corresponding update for Ubuntu 16.04 ESM. Dnsmasq has been updated to 2.79-1 for Ubuntu 16.04 ESM in order to fix some security issues. Petr Mensik discovered that Dnsmasq incorrectly randomized source ports in certain configurations. A remote attacker could possibly use this issue to facilitate DNS cache poisoning attacks.

GoCD is a continuous delivery server. Windows installations via either the server or agent installers for GoCD prior to 22.2.0 do not adequately restrict permissions when installing outside of the default location. This could allow a malicious user with local access to the server GoCD Server or Agent are installed on to modify executables or components of the installation. This does not affect zip file-based installs, installations to other platforms, or installations inside `Program Files` or `Program Files (x86)`. This issue is fixed in GoCD 22.2.0 installers. As a workaround, if the server or agent is installed outside of `Program Files (x86)`, verify the the permission of the Server or Agent installation directory to ensure the `Everyone` user group does not have `Full Control`, `Modify` or `Write` permissions.
