NVD Description

Note: Versions mentioned in the description apply only to the upstream webkit2gtk3-jsc-devel package and not the webkit2gtk3-jsc-devel package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2022 relevant fixed versions and status.

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.
