Lawrence Livermore National Laboratory’s decades of leadership in developing high-energy lasers is being tapped to provide a key component of a major upgrade to SLAC National Accelerator Laboratory’s Linac Coherent Light Source (LCLS).

Over the next several years, LLNL’s Advanced Photon Technologies (APT) program will design and construct one of the world’s most powerful petawatt (quadrillion-watt) laser systems for installation in an upgraded Matter in Extreme Conditions (MEC) experimental facility at LCLS, funded by the Department of Energy’s Office of Science-Fusion Energy Sciences program.

The new laser will pair with the LCLS X-ray free-electron laser (XFEL) to advance the understanding of high-energy density (HED) physics, plasma physics, fusion energy, laser-plasma interactions, astrophysics, planetary science and other physical phenomena.

When genes are activated and expressed, they show patterns in cells that are similar in type and function across tissues and organs. Discovering these patterns improves our understanding of cells—which has implications for unveiling disease mechanisms.

The advent of spatial transcriptomics technologies has allowed researchers to observe gene expression in their spatial context across entire tissue samples. But new computational methods are needed to make sense of this data and help identify and understand these .

A research team led by Jian Ma, the Ray and Stephanie Lane Professor of Computational Biology in Carnegie Mellon University’s School of Computer Science, has developed a machine learning tool to fill this gap. Their paper on the method, called SPICEMIX, appeared as the cover story in the most recent issue of Nature Genetics.

Designers including Philippe Starck and Titi Ogufere share their predictions for 2023’s major design trends, from the continued rise of AI to how inflation could impact the industry.

To mark the start of 2023, Dezeen asked 10 designers and industry experts to share the materials, technologies and influences that they think are set to dominate design trends this year.

The Guardian dice que un incidente cibernético a fines de diciembre de 2022 que provocó que el periódico britånico cerrara sus oficinas durante semanas fue causado por ransomware e informó al personal el miércoles que los hackers habían accedido a sus datos.

Un correo electrĂłnico enviado a su personal por la directora ejecutiva de Guardian Media Group Anna Bateson y la editora en jefe Katharine Viner dijeron que el ataque probablemente fue provocado por un correo electrĂłnico de phishing.

El diario no entregĂł detalles de los datos expuestos aunque aclarĂł que no se ha visto afectado ningĂșn dato personal de sus lectores o del personal en sus oficinas de EE.UU. o Australia.

This flaw, which has been identified that affects the ksmbd NTLMv2 authentication in the Linux kernel, is known to quickly cause the operating system on Linux-based computers to crash. Namjae Jeon is the developer of KSMBD, which is an open-source In-kernel CIFS/SMB3 server designed for the Linux Kernel. It is an implementation of the SMB/CIFS protocol in the kernel space that allows for the sharing of IPC services and files over a network.

In order to take advantage of the vulnerability, you will need to transmit corrupted packets to the server, personal computer, tablet, or smartphone that you are targeting. The attack causes what is known as “a memory overflow flaw in ksmbd decodentlmssp auth blob,” which states that nt len may be less than CIFS ENCPWD SIZE in some circumstances. Because of this, the blen parameter that is sent to ksmbd authntlmv2, which runs memcpy using blen on memory that was allocated by kmalloc(blen + CIFS CRYPTO KEY SIZE), is now negative. It is important to take note that the CIFS ENCPWD SIZE value is 16, and the CIFS CRYPTO KEY SIZE value is 8. As the heap overflow happens when blen is in the range [-8,-1], we think that the only possible outcome of this problem is a remote denial of service and not a privilege escalation or a remote code execution.

The vulnerability is caused by the way that the Linux kernel handles NTLMv2 authentication in versions 5.15-rc1 and later. The developers of the Linux kernel have not made a fix available.

La vulnerabilidad afecta a los instaladores de Rooms para Windows anteriores a la versiĂłn 5.13.0.

“Un usuario local con pocos privilegios podría explotar esta vulnerabilidad en una cadena de ataque para escalar sus privilegios al usuario del SISTEMA”. lee el aviso publicado por la empresa.

CVE-2022–36929 – (puntuación CVSS 7.8) – Aumento de privilegios locales en salas para clientes de Windows.

Researchers from the cyber security firm Imperva Red Team have disclosed information on a newly found and fixed vulnerability that affected over 2.5 billion Google Chrome users as well as all Chromium-based browsers such as Edge and Opera.

The vulnerability, which is identified as CVE-2022–3656, makes it possible for remote attackers to acquire sensitive user data such as passwords for cloud service providers and knowledge about cryptocurrency wallets. After further investigation, it was determined that the problem was caused by the manner in which the Chrome browser dealt with symlinks when processing directories and files.

Because of this vulnerability, an attacker can use social engineering to convince a victim to visit a website that has been compromised and then download a ZIP archive file from that website. The file will contain a symlink to a valuable folder or file that is already present on the device, such as wallet keys. The user is requested to input their recovery keys whenever this file is sent back to this site as a component of an infection chain, such as a crypto wallet service.
