SQLite before 3.25.3, when the FTS3 extension is enabled, encounters an
integer overflow (and resultant buffer overflow) for FTS3 queries in a
“merge” operation that occurs after crafted changes to FTS3 shadow tables,
allowing remote attackers to execute arbitrary code by leveraging the
ability to run arbitrary SQL statements (such as in certain WebSQL use
cases). This is a different vulnerability than CVE-2018-20346.
