Comment 6 Mauro Matteo Cascella 2020-02-18 17:18:44 UTC
The out-of-bounds read flaw lies in function propagateConstantExprRewrite() in src/select.c, which is part of the WHERE-clause constant propagation optimization.

The initial implementation of this feature was introduced in SQLite upstream version 3.25.0 with commit https://github.com/sqlite/sqlite/commit/660ee55663fb8aa26a7ebd764ec5c94440bcd62f.

Comment 7 Mauro Matteo Cascella 2020-02-18 17:21:52 UTC

This flaw did not affect the versions of SQLite as shipped with Red Hat Enterprise Linux 5, 6 and 7 as they did not include the WHERE-clause constant propagation optimization, which was introduced in a later version of the package.
