An improper authorization vulnerability in Darktrace mobile app (Android) prior to version 6.0.15 allows disabled and low-privilege users to control "antigena" actions(block/unblock traffic) from the mobile application. This vulnerability could create a "shutdown", blocking all ingress or egress traffic in the entire infrastructure where darktrace agents are deployed.

### Impact The use of Python's marshal module to handle unchecked input in a public method on `PortalFolder` objects can lead to an unauthenticated denial of service and crash situation. The code in question is exposed by all portal software built on top of `Products.CMFCore`, such as Plone. All deployments are vulnerable. ### Patches The code has been fixed in `Products.CMFCore` version 3.2. ### Workarounds Users can make the affected `decodeFolderFilter` method unreachable by editing the `PortalFolder.py` module in `Products.CMFCore` by hand and then restarting Zope. Go to line 233 of `PortalFolder.py` and remove both the `@security.public` decorator for `decodeFolderFilter` as well as the method's entire docstring. This is safe because the method is not actually used by current code. ### References - Products.CMFCore security advisory [GHSA-4hpj-8rhv-9x87](https://github.com/zopefoundation/Products.CMFCore/security/advisories/GHSA-4hpj-8rhv-9x87) ### Credits Thanks go to Nicolas...

A divide by zero issue discovered in Kodi Home Theater Software 19.5 and earlier allows attackers to cause a denial of service via use of crafted mp3 file.

There is an unauthenticated buffer overflow vulnerability in the process controlling the ArubaOS web-based management interface. Successful exploitation of this vulnerability results in a Denial-of-Service (DoS) condition affecting the web-based management interface of the controller.

Ubuntu Security Notice 6203-1 - Seokchan Yoon discovered that Django incorrectly handled certain regular expressions. A remote attacker could possibly use this issue to cause Django to consume resources, leading to a denial of service.

Ubuntu Security Notice 6202-1 - David Korczynski and Adam Korczynski discovered that containerd incorrectly processed certain images with large files. An attacker could possibly use this issue to cause containerd to crash, resulting in a denial of service. It was discovered that containerd incorrectly set up supplementary groups inside a container. An attacker with direct access to the container could possibly use this issue to obtain sensitive information or execute code with higher privileges.

Ubuntu Security Notice 6201-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Martin Hostettler discovered that Firefox did not properly block storage of all cookies when configured. An attacker could potentially exploits this issue to store tracking data without permission in localstorage.

The npm registry for the Node.js JavaScript runtime environment is susceptible to what's called a manifest confusion attack that could potentially allow threat actors to conceal malware in project dependencies or perform arbitrary script execution during installation. "A npm package's manifest is published independently from its tarball," Darcy Clarke, a former GitHub and npm engineering manager

Ubuntu Security Notice 6200-1 - It was discovered that ImageMagick incorrectly handled the "-authenticate" option for password-protected PDF files. An attacker could possibly use this issue to inject additional shell commands and perform arbitrary code execution. This issue only affected Ubuntu 20.04 LTS. It was discovered that ImageMagick incorrectly handled certain values when processing PDF files. If a user or automated system using ImageMagick were tricked into opening a specially crafted PDF file, an attacker could exploit this to cause a denial of service. This issue only affected Ubuntu 20.04 LTS.

Ubuntu Security Notice 6198-1 - It was discovered that GNU Screen was not properly checking user identifiers before sending certain signals to target processes. If GNU Screen was installed as setuid or setgid, a local attacker could possibly use this issue to cause a denial of service on a target application.
