Hi Heiko,
Good find, but why no embargo?


The issue was reported publicly via our bugtracker. No point in having
an embargo.

Presumably because privs are dropped so this is maybe not as bad as previous?


Yes, the privs are dropped in the reported case, but there may be other ways to call the
vulnerable function.

    Best regards from Dresden/Germany
    Viele Grüße aus Dresden
