Chrome: a recursive search on the libraries linked to in Chrome on OSX shows that the OSX system wide Address Book uses OpenSSL. Specifically LDAP. Here is the dependency tree that leads to OpenSSL on OSX Mavericks: /Applications/Google Chrome.app/Contents/MacOS/Google Chrome /Applications/Google Chrome.app/Contents/Versions/34.0.1788.0/Google Chrome Framework.framework/Google Chrome Framework /System/Library/Frameworks/AddressBook.framework/Versions/A/AddressBook /System/Library/Frameworks/LDAP.framework/Versions/A/LDAP /usr/lib/libssl.0.9.8.dylib $ strings /usr/lib/libssl.0.9.8.dylib | egrep '^OpenSSL' OpenSSL 0.9.8y 5 Feb 2013 0.9.8 is not effected so Chrome on OSX should be fine. (src: https://www.cert.fi/en/reports/2014/vulnerability788210.html https://www.cert.fi/en/reports/2014/vulnerability788210.html -- versions 1.0.1 to 1.0.1f) Safari: A similar search of safari shows some inclusion of OpenSSL code in the system wide Security.framework as a part of libsecurity_apple_csp. It is unlikely the bug crossed over as the inclusion is limited. $ strings /System/Library/Frameworks/Security.framework/Versions/A/Security \ | grep OpenSSL OpenSSL DH Method OpenSSL DSA method Firefox: On OSX it is using the same security framework as safari.
