writes "Ever since the Heartbleed flaw in OpenSSL was made public there have been various questions about who knew what and when. The Sydney Morning Herald has done some analysis of public mailing lists and talked to those involved with disclosing the bug to get the bottom of it. The newspaper finds that Google discovered Heartbleed on or before March 21 and notified OpenSSL on April 1. Other key dates include Finnish security testing firm Codenomicon discovering the flaw independently of Google at 23:30 PDT, April 2. SuSE, Debian, FreeBSD and AltLinux all got a heads up from Red Hat about the flaw in the early hours of April 7 — a few hours before it was made public. Ubuntu, Gentoo and Chromium attempted to get a heads up by responding to an email with few details about it but didn't get a heads up, as the guy at Red Hat sending the disclosure messages out in India went to bed. By the time he woke up, Codenomicon had reported the bug to OpenSSL and they freaked out and decided to tell the world about it."
