Background - -FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is -a collaborative effort to develop a robust, commercial-grade, full-featured -Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) -and Transport Layer Security (TLS v1) protocols as well as a full-strength -general purpose cryptography library. - -The SSL alert protocol is a way to communicate problems within a SSL/TLS session. - -II. Problem Description - -Due to improper handling of alert packets, OpenSSL would consume an excessive -amount of CPU time processing undefined alert messages. - -III. Impact - -A remote attacker who can initiate handshakes with an OpenSSL based server -can cause the server to consume a lot of computation power with very little -bandwidth usage, and may be able to use this technique in a leveraged Denial -of Service attack. - -IV. Workaround - -No workaround is available. - -V. Solution - -Perform one of the following: - -1) Upgrade your vulnerable system to a supported FreeBSD stable or -release / security branch (releng) dated after the correction date. - -Restart all daemons that use the library, or reboot the system. - -2) 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 - -Restart all daemons that use the library, or reboot the system. - -3) 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 10.x] -# fetch https://security.FreeBSD.org/patches/SA-16:35/openssl-10.patch -# fetch https://security.FreeBSD.org/patches/SA-16:35/openssl-10.patch.asc -# gpg --verify openssl-10.patch.asc - -[FreeBSD 9.3] -# fetch https://security.FreeBSD.org/patches/SA-16:35/openssl-9.patch -# fetch https://security.FreeBSD.org/patches/SA-16:35/openssl-9.patch.asc -# gpg --verify openssl-9.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.
