Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability is in the WebKit component; detection should focus on WebKit-based browsers and rendering engines processing maliciously crafted web content leading to process memory disclosure. ↗
- →On Linux/Debian systems, flag unpatched webkit2gtk packages older than version 2.38.3-1 (or 2.38.3-1~deb11u1 on bullseye) as vulnerable. ↗
- →On Red Hat systems, webkitgtk and webkitgtk3 packages are out of support scope and remain unpatched; treat any deployment of these packages as a persistent risk indicator. ↗
- ·The vulnerability affects multiple Apple platforms; patched versions are Safari 16.2, tvOS 16.2, macOS Ventura 13.1, iOS/iPadOS 15.7.2, iOS/iPadOS 16.2, and watchOS 9.2. Devices running older versions remain vulnerable. ↗
- ·The flaw is rooted in improper input validation leading to memory corruption; exploitation requires the target to process attacker-controlled web content, meaning network access is a prerequisite for remote exploitation. ↗

CVE-2022-46699 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.
