The easiest way to update Chrome is to allow it to update automatically, which basically uses the same method as outlined below but does not require your attention. In software exploit code, two common areas that are targeted for overflows are the stack and the heap. The heap is the portion of memory where dynamically allocated memory resides.
A buffer overflow is a type of software vulnerability that exists when an area of memory within a software application reaches its address boundary and writes into an adjacent memory region. The attacker would have to trick the victim to visit a specially crafted website.ĬVE-2022-2853: a heap buffer overflow in Downloads. SwiftShader is a an open source library that provides a software 3D renderer. A remote attacker can trick the victim to open a specially crafted web page and execute arbitrary code on the target system.ĬVE-2022-2854: a UAF vulnerability in SwiftShader. Google is aware that an exploit for CVE-2022-2856 exists in the wild. Google’s Threat Analysis Group submitted the vulnerability and technical details will not be released until everyone has had ample opportunity to update. Chrome intents are the deep linking replacement for URI schemes on the Android device within the Chrome browser. The Federated Credential Management API (FedCM) allows the browser to understand the context in which the relying party (for example a website) and the identity provider (a third party authentication service) exchange information.ĬVE-2022-2856: Insufficient validation of untrusted input in Intents. If after freeing a memory location, a program does not clear the pointer to that memory, an attacker can use the error to manipulate the program. Use after free (UAF) vulnerabilities occur because of the incorrect use of dynamic memory during a program’s operation. We discuss some of the CVE’s included in this update below.ĬVE-2022-2852: a critical use after free vulnerability in FedCM. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. One of the vulnerabilities is labeled as “Critical” and one of the vulnerabilities that is labeled as “High” exists in the wild.
Extended stable channel has been updated to 1.101 for Mac and 1.102 for Windows, which will roll out over the coming days/weeks. Google updated the Stable channel for Chrome to 1.101 for Mac and Linux and 1.102/101 for Windows which will roll out over the coming days/weeks.
