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....

Debian Linux Security Advisory 5642-1 - Three security issues were discovered in php-svg-lib, a PHP library to read, parse and export to PDF SVG files, which could result in denial of service, restriction bypass or the execution of arbitrary code.

Ubuntu Security Notice 6707-1 - Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element deactivation in certain cases, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

A local attacker could use this to cause a denial of service. It was discovered that the ARM Mali Display Processor driver implementation in the Linux kernel did not properly handle certain error conditions. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6706-1 - It was discovered that the Microchip USB Ethernet driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could use this to cause a denial of service.

Ubuntu Security Notice 6701-2 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service.
