HCE2-SA-2023-0230 Important HCE 2.0 Security Fix(es): A flaw was found in the webkitgtk package. An out of bounds read may be possible when processing malicious web content, which can lead to information disclosure. (CVE-2023-28204) BubblewrapLauncher.cpp in WebKitGTK and WPE WebKit before 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) A use after free vulnerability was found in the webkitgtk package. Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2023-32373) A flaw was found in the WebGPU, part of the Webkit project. This flaw allows a remote attacker to break out of the Web Content sandbox.
