1 Introduction

This errata document contains “late-breaking news” about FreeBSD 7.4-RELEASE. Before installing this version, it is important to consult this document to learn about any post-release discoveries or problems that may already have been found and fixed.

Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the “current errata” for this release. These other copies of the errata are located at, plus any sites which keep up-to-date mirrors of this location.

4 Late-Breaking News and Corrections

A bug in OpenSSL that could cause it to parse past the end of the message was found at the late stage of 7.4-RELEASE release process. The 7.4-RELEASE includes a fix for this issue by importing relevant parts from the OpenSSL CVS. This could be triggered by an incorrectly formatted ClientHello SSL/TLS handshake messages. The details can be found at

The shared object version numbers of libcrypto and libssl have been decreased from 6 to 5. These are accidentaly increased on 28 November, 2010 (r215997) as OpenSSL 0.9.8p was merged. Note that this affects systems running 7-STABLE after that date (after 7.3-RELEASE), not 7.3-RELEASE and the security branch. Also note that in FreeBSD 7.4-RELEASE, the library files with the version number 6 are still provided as symbolic links to prevent binaries built in the time window with the accidentaly increased version number from being broken after the system gets updated to 7.4-RELEASE.
