This update, to the current upstream stable release, includes a pair of security fixes :
Enable OpenSSL countermeasure against SSLv3/TLSv1 BEAST attacks (upstream bug 3704); to disable this countermeasure, which may cause interoperability issues with some clients, use the NoEmptyFragments TLSOption
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
