Ubuntu Security Notice 6704-1 - 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.

We now have new information on the entire kill chain this actor uses, including the tactics, techniques and procedures (TTPs) utilized to steal valuable information from their victims and propagate through their infected enterprises.

Using crafted public RSA keys which are not compliant with SP 800-56B can cause a small memory leak when encrypting and verifying payloads. An attacker can leverage this flaw to gradually erode available memory to the point where the host crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service.

There is also a newly disclosed vulnerability in a graphics driver for some NVIDIA GPUs that could lead to a memory leak.

Research conducted by Cisco Talos last year uncovered multiple vulnerabilities rated as low severity despite their ability to allow for full arbitrary code execution.

A new phishing campaign is targeting U.S. organizations with the intent to deploy a remote access trojan called NetSupport RAT. Israeli cybersecurity company Perception Point is tracking the activity under the moniker Operation PhantomBlu. "The PhantomBlu operation introduces a nuanced exploitation method, diverging from NetSupport RAT’s typical delivery mechanism by leveraging OLE (Object
