-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 ============================================================================FreeBSD-EN-19:03.sqlite Errata Notice The FreeBSD Project Topic: sqlite update Category: contrib Module: sqlite3 Announced: 2019-01-09 Credits: Cy Schubert Affects: All supported versions of FreeBSD. Corrected: 2018-12-21 01:58:01 UTC (stable/12, 12.0-STABLE) 2019-01-09 18:47:10 UTC (releng/12.0, 12.0-RELEASE-p2) 2018-12-21 02:04:15 UTC (stable/11, 11.2-STABLE) 2019-01-09 18:50:27 UTC (releng/11.2, 11.2-RELEASE-p8) CVE Name: CVE-2018-20346, CVE-2018-20505, CVE-2018-20506 For general information regarding FreeBSD Errata Notices and Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>. I. Background SQLite is an SQL database engine in a C library. Programs that link the SQLite library can have SQL database access without running a separate RDBMS process. The distribution comes with a standalone command-line access program (sqlite3) that can be used to administer an SQLite database and which serves as an example of how to use the SQLite library. II. Problem Description According to https://blade.tencent.com/magellan/index_en.html, the vulnerabilities known as Magellan are a group vulnerabilities that exist in sqlite3, documented by CVE-2018-20346, CVE-2018-20505, and CVE-2018-20506. When the FTS3 extension is enabled an integer overflow resulting in a buffer overflow when allowing remote attackers to run arbitrary SQL statements which can be leveraged to execute arbitrary code. III. Impact The vulnerabilities were discovered by Tencent Blade Team and verified to be able to successfully implement remote code execution in Chromium browsers. IV. Workaround No workaround is available. V. Solution Perform one of the following: 1) Upgrade your system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. 2) To update your system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install 3) To update your system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. [FreeBSD 11.2] # fetch https://security.FreeBSD.org/patches/EN-19:03/sqlite-11.patch # fetch https://security.FreeBSD.org/patches/EN-19:03/sqlite-11.patch.asc # gpg --verify sqlite-11.patch.asc [FreeBSD 12.0] # fetch https://security.FreeBSD.org/patches/EN-19:03/sqlite-12.patch # fetch https://security.FreeBSD.org/patches/EN-19:03/sqlite-12.patch.asc # gpg --verify sqlite-12.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system using buildworld and installworld as described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>. Restart all daemons that use the library, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch. Branch/path Revision - ------------------------------------------------------------------------- stable/12/ r342291 releng/12.0/ r342895 stable/11/ r342292 releng/11.2/ r342896 - ------------------------------------------------------------------------- To see which files were modified by a particular revision, run the following command, replacing NNNNNN with the revision number, on a machine with Subversion installed: # svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NNNNNN with the revision number: <URL:https://svnweb.freebsd.org/base?view=revision&revision=NNNNNN> VII.
