Description Guilherme de Almeida Suckevicz 2019-12-16 18:19:59 UTC

lookupName in resolve.c in SQLite 3.30.1 omits bits from the colUsed bitmask in the case of a generated column, which allows attackers to cause a denial of service or possibly have unspecified other impact.

Comment 3 Huzaifa S. Sidhpurwala 2020-02-21 06:03:24 UTC

Statement:

This flaw only affects sqlite databases which contain generated columns. The support for generated columns was added to sqlite-3.31.0 (https://sqlite.org/gencol.html). Therefore sqlite packages shipped with Red Hat products are not vulnerable to this flaw.
