CVE-2023-32393 WebKitGTK vulnerabilities
Title: WebKitGTK vulnerabilities
Summary: Several security issues were fixed in WebKitGTK.
Several security issues were discovered in the WebKitGTK Web and JavaScript
engines. If a user were tricked into viewing a malicious website, a remote
attacker could exploit a variety of issues related to web browser security,
including cross-site scripting attacks, denial of service attacks, and
arbitrary code execution.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart any applications
that use WebKitGTK, such as Epiphany, to make all the necessary changes.

USB Restricted Mode is a security feature ( introduced almost seven years ago in iOS 11.4.1) that blocks USB accessories from creating a data connection if the device has been locked for over an hour. This feature is designed to block forensic software like Graykey and Cellebrite (commonly used by law enforcement) from extracting data from locked iOS devices.
In November, Apple introduced another security feature (dubbed "inactivity reboot") that automatically restarts iPhones after long idle times to re-encrypt data and make it harder to extract by forensic software.

When the phones received and processed the attachment, it installed NSO's Pegasus spyware, even on fully patched iOS (16.6) devices.
Apple released fixes for the two flaws with macOS Ventura 13.5.2, iOS 16.6.1, iPadOS 16.6.1, and watchOS 9.6.2, and CISA published an alert requiring federal agencies to patch by October 2, 2023.
The security updates have now been backported to iOS 15.7.9 and iPadOS 15.7.9 , macOS Monterey 12.6.9 , and macOS Big Sur 11.7.10 to prevent the use of this attack chain on those devices.
It's worth noting that support for iOS 15 ended a year ago, in September 2022, while the vendor still supports Monterey and Big Sur.
The security updates cover all iPhone 6s models, the iPhone 7, the fir

"The exploit involved PassKit attachments containing malicious images sent from an attacker iMessage account to the victim."
Citizen Lab also urged Apple customers to update their devices immediately and encouraged those at risk of targeted attacks due to their identity or profession to activate Lockdown Mode .
Apple and Citizen Lab security researchers discovered the two zero-days in the Image I/O and Wallet frameworks.
CVE-2023-41064 is a buffer overflow triggered when processing maliciously crafted images, while CVE-2023-41061 is a validation issue that can be exploited via malicious attachments.
Both allow threat actors to gain arbitrary code execution on unpatched iPhone and iPad devices.

Citizen Lab also revealed today that the CVE-2023-41064 and CVE-2023-41061 bugs were actively abused as part of as part of a zero-click iMessage exploit chain named BLASTPASS that was used to deploy NSO Group's Pegasus mercenary spyware onto fully-patched iPhones (running iOS (16.6) via PassKit attachments containing malicious images.
CVE-2023-41064 is a buffer overflow weakness that gets triggered when processing maliciously crafted images, and it can lead to arbitrary code execution on unpatched devices.
CVE-2023-41061 is a validation issue that can be exploited using a malicious attachment to also gain arbitrary code execution on targeted devices.

## It’s apparently hip to still be using Windows 7
Welcome to this week’s edition of the Threat Source newsletter.
As a longtime macOS user, I must admit I’m behind the times when it comes to Microsoft Windows. Since buying a Steam Deck, I’ve actually come to learn more about Linux and the Proton compatibility layer than I ever did about Windows.
But it still came as a shock to me this week when I uncovered a weird trend on social media: People bragging about still using Windows 7.
Microsoft stopped putting out free security updates for Windows 7 in January 2020 and only more recently stopped offering its paid Extended Security Updates (ESU) . The company explicitly told users at the beginning of this year that it was unsafe to continue to keep using Windows 7 and that users should upg
