    For general information regarding FreeBSD 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.

    FreeBSD includes SQLite as a private library for base system usage that is
    not generally exposed for third party packages to use.

    II. Problem Description

    Multiple vulnerabilities have been published including improper input validation (CVE-2020-11655), use after free (CVE-2020-11656, CVE-2020-13630), integer overflow (CVE-2020-13434), null pointer dereference (CVE-2020-13435, CVE-2020-13632), and namespace collision (CVE-2020-13631).

    III. Impact

    Malicious SQL statements could crash, hijack processes, or cause data corruption.

    IV. Workaround

    No workaround is available. The FreeBSD security team is not aware of any
    base system components that use SQLite in such a way as to expose these vulnerabilities to untrusted or remote users, but is updating SQLite out of
    an abundance of caution.

    V. Solution

    Upgrade your vulnerable system to a supported FreeBSD stable or
    release / security branch (releng) dated after the correction date.

    Perform one of the following:

    1) To update your vulnerable 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
    # shutdown -r +10min "Rebooting for a security update"

    2) To update your vulnerable 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 12.1]
    # fetch https://security.FreeBSD.org/patches/SA-20:21/sqlite.12.1.patch
    # fetch https://security.FreeBSD.org/patches/SA-20:21/sqlite.12.1.patch.asc
    # gpg --verify sqlite.12.1.patch.asc

    [FreeBSD 11.4]
    # fetch https://security.FreeBSD.org/patches/SA-20:21/sqlite.11.4.patch
    # fetch https://security.FreeBSD.org/patches/SA-20:21/sqlite.11.4.patch.asc
    # gpg --verify sqlite.11.4.patch.asc

    [FreeBSD 11.3]
    # fetch https://security.FreeBSD.org/patches/SA-20:21/sqlite.11.3.patch
    # fetch https://security.FreeBSD.org/patches/SA-20:21/sqlite.11.3.patch.asc
    # gpg --verify sqlite.11.3.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/ r362190 releng/12.1/ r363922 stable/11/ r362190 releng/11.4/ r363922 releng/11.3/ r363922
    - -------------------------------------------------------------------------

    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>
