"An updated sqlite package that fixes one security issue is now
available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link 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.

It was found that SQLite's sqlite3VXPrintf() function did not properly
handle precision and width values during floating-point conversions. A
local attacker could submit a specially crafted SELECT statement that
would crash the SQLite process, or have other unspecified impacts.
(CVE-2015-3416)

All sqlite users are advised to upgrade to this updated package, which
contains a backported patch to correct this issue."
