Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.

No cwe for this issue in Windows Virtualization-Based Security (VBS) Enclave allows an authorized attacker to elevate privileges locally.

The new ransomware strain's aggressive multithreading and cross-platform capabilities make it a potent threat to enterprise environments.

The Call of Duty team confirmed that the PC edition of WWII has been taken offline following "reports of an issue."

This Fourth of July, Bruce, the 25-foot mechanical shark from Jaws, shares how his saltwater struggles mirror the need for real-world cybersecurity stress testing.

An authenticated virtual machine escape vulnerability exists in HashiCorp Vagrant versions 2.4.6 and below when using the default synced folder configuration. By design, Vagrant automatically mounts the host system’s project directory into the guest VM under /vagrant (or C:\vagrant on Windows). This includes the Vagrantfile configuration file, which is a Ruby script evaluated by the host every time a vagrant command is executed in the project directory. If a low-privileged attacker obtains shell access to the guest VM, they can append arbitrary Ruby code to the mounted Vagrantfile. When a user on the host later runs any vagrant command, the injected code is executed on the host with that user’s privileges. While this shared-folder behavior is well-documented by Vagrant, the security implications of Vagrantfile execution from guest-writable storage are not explicitly addressed. This effectively enables guest-to-host code execution in multi-tenant or adversarial VM scenarios.

Google has released an urgent update for the Chrome browser to patch a vulnerability which has already been exploited.

electron's ASAR Integrity can be bypass by modifying the content. ### Impact This only impacts apps that have the `embeddedAsarIntegrityValidation` and `onlyLoadAppFromAsar` [fuses](https://www.electronjs.org/docs/latest/tutorial/fuses) enabled. Apps without these fuses enabled are not impacted. This issue is specific to Windows, apps using these fuses on macOS are unimpacted. Specifically this issue can only be exploited if your app is launched from a filesystem the attacker has write access too. i.e. the ability to edit files inside the .app bundle on macOS which these fuses are supposed to protect against. ### Workarounds There are no app side workarounds, you must update to a patched version of Electron. ### Fixed Versions * `30.0.5` * `31.0.0-beta.1` ### For more information If you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)
