I. Background FreeBSD includes Heimdal, an implementation of ASN.1/DER, PKIX, and Kerberos. It uses OpenSSL to provide a number of cryptographic routines. II. Problem Description Weak crypto is provided by the openssl "legacy" provider which is not loaded by default. III. Impact Attempting to use weak crypto routines when the legacy provider is not loaded results in the application crashing. IV. Workaround Edit /etc/ssl/openssl.cnf to load the legacy provider unconditionally. V. Solution Upgrade your 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 system via a binary patch: Systems running a RELEASE version of FreeBSD on the amd64 or arm64 platforms, or the i386 platform on FreeBSD 13, can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install 2) 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. # fetch https://security.FreeBSD.org/patches/EN-24:08/kerberos.patch # fetch https://security.FreeBSD.org/patches/EN-24:08/kerberos.patch.asc # gpg --verify kerberos.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 . Restart all daemons that use the library, or reboot the system. VI. Correction details This issue is corrected as of the corresponding Git commit hash in the following stable and release branches: Branch/path Hash Revision - ------------------------------------------------------------------------- stable/14/ c7db2e15e404 stable/14-n266467 releng/14.0/ c48fe39ad139 releng/14.0-n265415 - ------------------------------------------------------------------------- Run the following command to see which files were modified by a particular commit: # git show --stat Or visit the following URL, replacing NNNNNN with the hash: To determine the commit count in a working tree (for comparison against nNNNNNN in the table above), run: # git rev-list --count --first-parent HEAD VII.
