Hi all,

Since this thread is public on LKML, as it should be, it's no longer
valid to be CC'ed to linux-distros, which is for handling of embargoed
issues only.  So please drop linux-distros from further CC's (I moved
linux-distros to Bcc on this reply, just so they know what happened).

If specific security issues are identified (such as with LibreOffice and
Java), then ideally those should be posted to oss-security as separate
reports.  I'd appreciate it if anyone takes care of that (regardless of
CVE worthiness).

In fact, I already mentioned this thread in:

Thank you!

Alexander
