A vulnerability has been discovered in OpenSSH that could allow for remote code execution. OpenSSH is a suite of secure networking utilities based on the SSH protocol and is crucial for secure communication over unsecured networks. It is widely used in enterprise environments for remote server management, secure file transfers, and various DevOps practices. Successful exploitation of this vulnerability could allow for remote code execution in the context of the unprivileged user running the sshd server. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

USN-6886-1: Go vulnerabilities
It was discovered that the Go net/http module did not properly handle the
requests when request’s headers exceed MaxHeaderBytes. An attacker could
possibly use this issue to cause a panic resulting into a denial of service.
This issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
(CVE-2023-45288)
It was discovered that the Go net/http module did not properly validate the
subdomain match or exact match of the initial domain. An attacker could
possibly use this issue to read sensitive information. This issue only
affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-45289)
It was discovered that the Go net/http module did not properly validate the
total size of the parsed form when parsing a multipart form. An attacker
could possibly use this issue to cause a panic resulting into a denial of
service. This issue only affected Go 1.21 in Ubuntu 20.04 LTS and Ubuntu
22.04 LTS. (CVE-2023-45290)
It was discovered that the Go crypto/x509 module did not properly handle a
