-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 ============================================================================= FreeBSD-EN-21:24.libcrypto Errata Notice The FreeBSD Project Topic: OpenSSL 1.1.1e API functions not exported Category: core Module: libcrypto Announced: 2021-08-24 Affects: FreeBSD 12.2 and later. Corrected: 2021-06-09 21:53:42 UTC (stable/13, 13.0-STABLE) 2021-08-24 17:25:47 UTC (releng/13.0, 13.0-RELEASE-p4) 2021-06-09 21:54:13 UTC (stable/12, 12.2-STABLE) 2021-08-24 18:32:08 UTC (releng/12.2, 12.2-RELEASE-p10) 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 libcrypto is part of the OpenSSL distribution and provides APIs to various low-level cryptographic services. II. Problem Description New API functions added in OpenSSL 1.1.1e and later were not publicly exported to applications. III. Impact Applications trying to use new API functions added in OpenSSL 1.1.1e or later would fail to build with a link error. IV. Workaround No workaround is available. However, the APIs added in OpenSSL 1.1.1e and later are obscure and not used by many applications. In particular, none of the affected APIs are used by applications using libssl from OpenSSL for Transport Layer Security (TLS). 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, i386, or (on FreeBSD 13 and later) arm64 platforms 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-21:17/libcrypto.patch # fetch https://security.FreeBSD.org/patches/EN-21:17/libcrypto.patch.asc # gpg --verify libcrypto.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>. VI. Correction details This issue is corrected by the corresponding Git commit hash or Subversion revision number in the following stable and release branches: Branch/path Hash Revision - ------------------------------------------------------------------------- stable/13/ f8edb3f9c725 stable/13-n245963 releng/13.0/ 3ef67fed446a releng/13.0-n244754 stable/12/ r369974 releng/12.2/ r370391 - ------------------------------------------------------------------------- For FreeBSD 13 and later: Run the following command to see which files were modified by a particular commit: # git show --stat <commit hash> Or visit the following URL, replacing NNNNNN with the hash: <URL:https://cgit.freebsd.org/src/commit/?id=NNNNNN> 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 For FreeBSD 12 and earlier: Run the following command to see which files were modified by a particular revision, replacing NNNNNN with the revision number: # 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.
