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

    • Response pool use-after-free memory corruption error (upstream bug 3711, #752812, ZDI-CAN-1420, CVE-2011-4130), in which a remote attacker could provide a specially crafted request (resulting in a need for the server to handle an exceptional condition), leading to memory corruption and potentially arbitrary code execution, with the privileges of the user running the proftpd server

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.
