Google has rolled out security updates for the Chrome web browser to address a high-severity zero-day flaw that it said has been exploited in the wild. The vulnerability, assigned the CVE identifier  CVE-2023-7024 , has been described as a  heap-based buffer overflow bug  in the WebRTC framework that could be exploited to result in program crashes or arbitrary code execution. Clément Lecigne and Vlad Stolyarov of Google's Threat Analysis Group (TAG) have been credited with discovering and reporting the flaw on December 19, 2023. No other details about the security defect have been released to prevent further abuse, with Google  acknowledging  that "an exploit for CVE-2023-7024 exists in the wild." Given that WebRTC is an open-source project and that it's also supported by Mozilla Firefox and Apple Safari, it's currently not clear if the flaw has any impact beyond Chrome and Chromium-based browsers. The development marks the resolution of the eighth activel...

In January 2019, a  critical flaw  was reported in Apple's FaceTime group chats feature that made it possible for users to initiate a FaceTime video call and eavesdrop on targets by adding their own number as a third person in a group chat even before the person on the other end accepted the incoming call. The vulnerability was deemed so severe that the iPhone maker removed the FaceTime group chats feature altogether before the issue was resolved in a subsequent iOS update. Since then, a number of similar shortcomings have been discovered in multiple video chat apps such as Signal, JioChat, Mocha, Google Duo, and Facebook Messenger — all thanks to the work of Google Project Zero researcher Natalie Silvanovich. "While [the Group FaceTime] bug was soon fixed, the fact that such a serious and easy to reach vulnerability had occurred due to a logic bug in a calling state machine — an attack scenario I had never seen considered on any platform — made me wonder whether other sta...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Facebook has patched a bug in its widely installed Messenger app for Android that could have allowed a remote attacker to call unsuspecting targets and listen to them before even they picked up the audio call. The flaw was discovered and reported to Facebook by  Natalie Silvanovich  of Google's Project Zero bug-hunting team last month on October 6 with a 90-day deadline, and impacts version 284.0.0.16.119 (and before) of Facebook Messenger for Android. In a nutshell, the vulnerability could have granted an attacker who is logged into the app to simultaneously initiate a call and send a specially crafted message to a target who is signed in to both the app as well as another Messenger client such as the web browser. "It would then trigger a scenario where, while the device is ringing, the caller would begin receiving audio either until the person being called answers or the call times out," Facebook's Security Engineering Manager Dan Gurfinkel  said . According t...
