Researchers warn that polymorphic malware created with ChatGPT and other LLMs will force a reinvention of security automation.

Red Hat Security Advisory 2023-1109-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system.

Red Hat Security Advisory 2023-1151-01 - Red Hat Satellite is a system management solution that allows organizations to configure and maintain their systems without the necessity to provide public Internet access to their servers or other client systems. It performs provisioning and configuration management of predefined standard operating environments.

Red Hat Security Advisory 2023-1110-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Red Hat Security Advisory 2023-1140-01 - The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. Issues addressed include a denial of service vulnerability.

Ubuntu Security Notice 5935-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Debian Linux Security Advisory 5370-1 - Ronald Crane discovered that missing input saniting in the apr_encode functions of apr, the Apache Portable Runtime library, may result in denial of service or potentially the execution of arbitrary code.

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 (system crash) 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 (system crash) or possibly execute arbitrary code. 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 (system crash) or possibly execute arbitrary code.

Red Hat Security Advisory 2023-1130-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include null pointer and use-after-free vulnerabilities.

Ubuntu Security Notice 5934-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service.
