Atlassian and the Internet Systems Consortium (ISC) have disclosed several security flaws impacting their products that could be exploited to achieve denial-of-service (DoS) and remote code execution. The Australian software services provider said that the four high-severity flaws were fixed in new versions shipped last month. This includes - CVE-2022-25647 (CVSS score: 7.5) - A deserialization

pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 2.5-41.0.3 are vulnerable to several security issues. More details about the vulnerabilities themselves can be found in https://www.openssl.org/news/secadv/20230908.txt. If you are building cryptography source ("sdist") then you are responsible for upgrading your copy of OpenSSL. Only users installing from wheels built by the cryptography project (i.e., those distributed on PyPI) need to update their cryptography versions.

Multiple TOTOLINK network products contain a command injection vulnerability in setting/setTracerouteCfg. This vulnerability allows an attacker to execute arbitrary commands through the command parameter. After exploitation, an attacker will have full access with the same user privileges under which the webserver is running - which is typically root.

Ubuntu Security Notice 6390-1 - It was discovered that Bind incorrectly handled certain control channel messages. A remote attacker with access to the control channel could possibly use this issue to cause Bind to crash, resulting in a denial of service. Robert Story discovered that Bind incorrectly handled certain DNS-over-TLS queries. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04.

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.

Red Hat Security Advisory 2023-5264-01 - 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.

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.
