Minecraft, with over 500 million registered users and 166 million monthly players, faces significant risks from distributed denial-of-service (DDoS) attacks, threatening server functionality, player experience, and the game’s reputation. Despite the prevalence of DDoS attacks on the game, the majority of incidents go unreported, leaving a gap in awareness and protection. This article explains

A flaw was found in XNIO. The XNIO NotifierState that can cause a Stack Overflow Exception when the chain of notifier states becomes problematically large can lead to uncontrolled resource management and a possible denial of service (DoS). Version 3.8.14.Final is expected to contain a fix.

Debian Linux Security Advisory 5644-1 - Multiple security issues were discovered in Thunderbird, which could result in denial of service, the execution of arbitrary code or leaks of encrypted email subjects.

Ubuntu Security Notice 6708-1 - It was discovered that Graphviz incorrectly handled certain config6a files. An attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 6709-1 - It was discovered that checking excessively long DH keys or parameters may be very slow. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service. After the fix for CVE-2023-3446 Bernd Edlinger discovered that a large q parameter value can also trigger an overly long computation during some of these checks. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service.

Ubuntu Security Notice 6700-2 - It was discovered that the Layer 2 Tunneling Protocol implementation in the Linux kernel contained a race condition when releasing PPPoL2TP sockets in certain conditions, 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 ext4 file system implementation in the Linux kernel did not properly handle block device modification while it is mounted. A privileged attacker could use this to cause a denial of service or possibly expose sensitive information.

Ubuntu Security Notice 6704-2 - It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service. Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly handle session setup requests. A remote attacker could possibly use this to cause a denial of service.

## Description: During some analysis today on npm's `node-tar` package I came across the folder creation process, Basicly if you provide node-tar with a path like this `./a/b/c/foo.txt` it would create every folder and sub-folder here a, b and c until it reaches the last folder to create `foo.txt`, In-this case I noticed that there's no validation at all on the amount of folders being created, that said we're actually able to CPU and memory consume the system running node-tar and even crash the nodejs client within few seconds of running it using a path with too many sub-folders inside ## Steps To Reproduce: You can reproduce this issue by downloading the tar file I provided in the resources and using node-tar to extract it, you should get the same behavior as the video ## Proof Of Concept: Here's a [video](https://hackerone-us-west-2-production-attachments.s3.us-west-2.amazonaws.com/3i7uojw8s52psar6pg8zkdo4h9io?response-content-disposition=attachment%3B%20filename%3D%22tar-dos-poc....
