Description Dhananjay Arunesh 2019-03-25 12:49:17 UTC 
In SQLite 3.27.2, interleaving reads and writes in a single transaction with an fts5 virtual table will lead to a NULL Pointer Dereference in fts5ChunkIterate in sqlite3.c. This is related to ext/fts5/fts5_hash.c and ext/fts5/fts5_index.c.

Comment 1 Dhananjay Arunesh 2019-03-25 12:50:35 UTC 
Created sqlite tracking bugs for this issue:

Affects: fedora-all [bug 1692358]
Comment 6 Marco Benatto 2019-03-29 19:20:32 UTC 
Statement:

This issue did not affect the versions of sqlite as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for fts5.
