Red Hat Security Advisory 2023-5313-01 - The Open Virtual Machine Tools are the open source implementation of the VMware Tools. They are a set of guest operating system virtualization components that enhance performance and user experience of virtual machines. Issues addressed include a bypass vulnerability.

The `PaperCutNG Mobility Print` version 1.0.3512 application allows an unauthenticated attacker to perform a CSRF attack on an instance administrator to configure the clients host (in the "configure printer discovery" section). This is possible because the application has no protections against CSRF attacks, like Anti-CSRF tokens, header origin validation, samesite cookies, etc.

Ubuntu Security Notice 6385-1 - It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. William Zhao discovered that the Traffic Control subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service.

Red Hat Security Advisory 2023-5239-01 - 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 buffer overflow, code execution, and denial of service vulnerabilities.

The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key; only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1.

A flaw in the networking code handling DNS-over-TLS queries may cause `named` to terminate unexpectedly due to an assertion failure. This happens when internal data structures are incorrectly reused under significant DNS-over-TLS query load. This issue affects BIND 9 versions 9.18.0 through 9.18.18 and 9.18.11-S1 through 9.18.18-S1.

Earlier this year, Red Hat engineering took a close look at how to accelerate compression within applications by using 4th Gen Intel Xeon Scalable Processors that include Intel® QuickAssist Technology (Intel® QAT), which can accelerate both compression and encryption. Today we will examine the encryption capabilities and show how to achieve major performance improvements with leading load balancing applications. HAProxy and F5’s NGINX were tested running on Red Hat Enterprise Linux 9.2. Setting up We started with a RHEL 9.2 installation on a system with an Intel Xeon Platinum 8480+ p

MiniTool Power Data Recovery 11.6 contains an insecure installation process that allows attackers to achieve remote code execution through a man in the middle attack.

Red Hat Security Advisory 2023-5255-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine- tuning for systems with extremely high determinism requirements. Issues addressed include information leakage, out of bounds write, and use-after-free vulnerabilities.
