Summary

The rubygem sqlite3 v1.5.1 upgrades the packaged version of libsqlite from v3.39.3 to v3.39.4.

libsqlite v3.39.4 addresses a vulnerability described as follows in the release notification:

Version 3.39.4 is a minimal patch against the prior release that addresses issues found since the
prior release. In particular, a potential vulnerability in the FTS3 extension has been fixed, so
this should be considered a security update.

In order to exploit the vulnerability, an attacker must have full SQL access and must be able to
construct a corrupt database with over 2GB of FTS3 content. The problem arises from a 32-bit
signed integer overflow.

This vulnerability has not been assigned a CVE and does not have a severity declared.

Please note that this advisory only applies to the sqlite3 gem v1.5.0, and only if the packaged libsqlite is being used. If you’ve overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro’s libsqlite release announcements.

Mitigation

Upgrade to the rubygem sqlite3 v1.5.1 or later.

Users who are unable to upgrade the sqlite3 gem may also choose a more complicated mitigation: compile and link sqlite3 against external libsqlite >= 3.39.4 which will also address these same issues.
