Description Guilherme de Almeida Suckevicz 2020-06-29 14:17:06 UTC 
In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.

Comment 2 Mauro Matteo Cascella 2020-07-09 08:49:19 UTC 
As noted here: https://www.sqlite.org/src/tktview?name=8f157e8010
this bug was apparently introduced in upstream version 3.25.0 with the new use of transitive properties for constant propagation.
Comment 4 Mauro Matteo Cascella 2020-07-09 08:58:57 UTC 
Statement:

This flaw did not affect the versions of SQLite as shipped with Red Hat Enterprise Linux 7 as they did not include support for the WHERE-clause constant propagation optimization. This optimization was introduced in a later version of the package (3.25.0).
