Mathematicians find odd shapes that roll like a wheel in any dimension

Mathematicians have reinvented the wheel with the discovery of shapes that can roll smoothly when sandwiched between two surfaces, even in four, five or any higher number of spatial dimensions. The finding answers a question that researchers have been puzzling over for decades. Such objects are known as shapes of constant width, and the most Read more about Mathematicians find odd shapes that roll like a wheel in any dimension[…]

ASUS Releases Firmware Update for Critical Remote Authentication Bypass Affecting Seven Routers

A report from BleepingComputer notes that ASUS “has released a new firmware update that addresses a vulnerability impacting seven router models that allow remote attackers to log in to devices.” But there’s more bad news: Taiwan’s CERT has also informed the public about CVE-2024-3912 in a post yesterday, which is a critical (9.8) arbitrary firmware Read more about ASUS Releases Firmware Update for Critical Remote Authentication Bypass Affecting Seven Routers[…]

Arm Memory Tag Extensions broken by speculative execution

In 2018, chip designer Arm introduced a hardware security feature called Memory Tagging Extensions (MTE) as a defense against memory safety bugs. But it may not be as effective as first hoped. Implemented and supported last year in Google’s Pixel 8 and Pixel 8 Pro phones and previously in Linux, MTE aims to help detect Read more about Arm Memory Tag Extensions broken by speculative execution[…]

Signal, MEPs urge EU Council to drop law that puts a spy on everyone’s devices

On Thursday, the EU Council is scheduled to vote on a legislative proposal that would attempt to protect children online by disallowing confidential communication. The vote had been set for Wednesday but got pushed back [PDF]. Known to detractors as Chat Control, the proposal seeks to prevent the online dissemination of child sexual abuse material Read more about Signal, MEPs urge EU Council to drop law that puts a spy on everyone’s devices[…]

Astronomers detect sudden awakening of black hole 1m times mass of sun

The mysterious brightening of a galaxy far, far away has been traced to the heart of the star system and the sudden awakening of a giant black hole 1m times more massive than the sun. Decades of observations found nothing remarkable about the distant galaxy in the constellation of Virgo, but that changed at the Read more about Astronomers detect sudden awakening of black hole 1m times mass of sun[…]

Wi-Fi Routers are like an trackers available to everyone

Apple and the satellite-based broadband service Starlink each recently took steps to address new research into the potential security and privacy implications of how their services geo-locate devices. Researchers from the University of Maryland say they relied on publicly available data from Apple to track the location of billions of devices globally — including non-Apple Read more about Wi-Fi Routers are like an trackers available to everyone[…]
