I don't think what you report has to do with the Heartbleed, unless your Lms runs on an https site with the OpenSSL certificate.
Is that your case?
What version of Chrome are you running?
Heartbleed OpenSSL issue is reletad with the crypto library used by web server in the https protocol.
Only few versions of the openssl library are affected: from 1.0.1 to 1.0.1e
Many of the linux platform was not affected by this bug .
All system administrators are encouraged to updated his/her systems to the new openssl library
But this issue does not affect the data transferred by the web server to the broswer.
Many users experiments problems with Chrome version 34 (released past week) and some flash versions . due to a modification to the JS interpreter. With this version of JS there is an incompatible bug with the Docebo Ce / formaLms scorm player
