‘Class pollution’ flaw similar to dangerous vulnerability type found in JavaScript and similar languages

Ubuntu Security Notice 5797-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

Red Hat Security Advisory 2023-0050-01 - Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Issues addressed include a denial of service vulnerability.

Ubuntu Security Notice 5796-1 - It was discovered that w3m incorrectly handled certain HTML files. A remote attacker could use this issue to cause w3m to crash, resulting in a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 5793-2 - It was discovered that the io_uring subsystem in the Linux kernel did not properly perform reference counting in some situations, 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 a race condition existed in the Android Binder IPC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5795-1 - It was discovered that Net-SNMP incorrectly handled certain requests. A remote attacker could possibly use these issues to cause Net-SNMP to crash, resulting in a denial of service.

Ubuntu Security Notice 5782-3 - USN-5782-1 fixed vulnerabilities in Firefox. The update introduced several minor regressions. This update fixes the problem. It was discovered that Firefox was using an out-of-date libusrsctp library. An attacker could possibly use this library to perform a reentrancy issue on Firefox. Nika Layzell discovered that Firefox was not performing a check on paste received from cross-processes. An attacker could potentially exploit this to obtain sensitive information. Pete Freitag discovered that Firefox did not implement the unsafe-hashes CSP directive. An attacker who was able to inject markup into a page otherwise protected by a Content Security Policy may have been able to inject an executable script. Matthias Zoellner discovered that Firefox was not keeping the filename ending intact when using the drag-and-drop event. An attacker could possibly use this issue to add a file with a malicious extension, leading to execute arbitrary code. Hafiizh discovered ...

Ubuntu Security Notice 5792-2 - Mingwei Zhang discovered that the KVM implementation for AMD processors in the Linux kernel did not properly handle cache coherency with Secure Encrypted Virtualization. A local attacker could possibly use this to cause a denial of service. It was discovered that a race condition existed in the Android Binder IPC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5791-2 - It was discovered that a race condition existed in the Android Binder IPC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering.

An issue was discovered in MediaWiki before 1.35.9, 1.36.x through 1.38.x before 1.38.5, and 1.39.x before 1.39.1. SpecialMobileHistory allows remote attackers to cause a denial of service because database queries are slow.
