Hi @ll, the current 3CXPhone6.msi (for Windows), available from <http://www.3cx.com/VOIP/sip-phone/>, digitally signed on 2012-07-30, installs the following outdated and vulnerable 3rd-party libraries: * libeay32.dll and ssleay32.dll version 0.9.8h (from 2008-05-28) of OpenSSL. The current version of OpenSSL is 0.9.8y, see <http://www.openssl.org/>, it fixes about 20 CVEs found in earlier versions downto 0.9.8h. * FFmpeg/FFdshow version 1.1.0 The current version of FFmpeg/FFdshow is 1.2, see <http://www.ffmpeg.org/security.html> for the 24 fixed CVEs since 1.1.0.
