"Dmitri Lenev discovered that arguments of setuid SQL functions were
evaluated in the security context of the functions' definer instead of
its caller. An authenticated user with the privilege to call such a
function could exploit this to execute arbitrary statements with the
privileges of the definer of that function. (CVE-2006-4227)

Peter Gulutzan reported a potentially confusing situation of the MERGE
table engine. If an user creates a merge table, and the administrator
later revokes privileges on the original table only (without changing
the privileges on the merge table), that user still has access to the
data by using the merge table. This is intended behaviour, but might
be undesirable in some installations; this update introduces a new
server option '--skip-merge' which disables the MERGE engine
completely. (CVE-2006-4031).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
