**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

Cybersecurity researchers have unearthed a new Python-based attack campaign that leverages a Python-based remote access trojan (RAT) to gain control over compromised systems since at least August 2022. "This malware is unique in its utilization of WebSockets to avoid detection and for both command-and-control (C2) communication and exfiltration," Securonix said in a report shared with The Hacker

The security vulnerability allows attackers to spoof a target certificate and masquerade as any website, among other things.

Red Hat Security Advisory 2023-0432-01 - Kernel-based Virtual Machine offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems. Issues addressed include an out of bounds read vulnerability.
