Description Carlos López 2021-10-22 06:45:17 UTC 
CVE-2021-42762

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.
