(CVE-2021-32912)\nBubblewrapLauncher.cpp in WebKitGTK and WPE WebKit prior to 2.34.1 allows a limited sandbox bypass that allows a sandboxed process to trick host processes into thinking the sandboxed process is not confined by the sandbox, by abusing VFS syscalls that manipulate its filesystem namespace. The impact is limited to host services that create UNIX sockets that WebKit mounts inside its sandbox, and the sandboxed process remains otherwise confined. NOTE: this is similar to CVE-2021-41133. (CVE-2021-42762)\nA segmentation violation vulnerability was found in webkitgtk. An attacker with network access could pass specially crafted HTML files causing an application to halt or crash.

(CVE-2021-45482)\nA use-after-free vulnerability was found in webkitgtk. An attacker with network access could pass specially crafted HTML files causing an application to halt or crash. Video self-preview in a webRTC call may be interrupted if the user answers a phone call. An app may be able to disclose kernel memory. Visiting a website that frames malicious content may lead to UI spoofing. Visiting a malicious website may lead to user interface spoofing. Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.1.. (CVE-2022-46700)\nA flaw was found in the WebKitGTK package. An improper input validation issue may lead to a use-after-free vulnerability. This may, in theory, allow a remote malicious user to create a specially crafted web page, trick the victim into opening it, trigger type confusion, and execute arbitrary code on the target system.
