"An update for sqlite is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

SQLite is a C library that implements a SQL database engine. A large
subset of SQL92 is supported. A complete database is stored in a
single disk file. The API is designed for convenience and ease of use.
Applications that link against SQLite can enjoy the power and
flexibility of a SQL database without the administrative hassles of
supporting a separate database server.

Security Fix(es) :

* sqlite: fts3: improve shadow table corruption detection
(CVE-2019-13734)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section."
