"The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by a vulnerability as referenced in
the SUSE-SU-2021:3603-1 advisory.

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
