Debian, Ubuntu flawed for two yearsRandom insecurity in online transactionsBy Stewart Meagher: Tuesday, 20 May 2008, 10:39 PMA RESEARCH POSTING to the Debian security list last week has led to the confirmation of a serious hole in two flavours of the Open Sauce Linux operating system.Frederick Lee, a researcher at insecurity company Fortify, said that the flaw, which affects Ubuntu as well as Debian, had been "seriously underestimated " as it makes the Secure Sockets Layer (SSL) of the two Linux sustems vulnerable to malicious attack."We're calling this vulnerability 'insecure randomness' since it allows an attacker to predict the SSL cryptographic keys used for supposedly secure online transactions," he said.Lee reckons that the flaw, which tinkers with the randomness engine used to encrypt secure transactions, could be used to intercept traffic between a user and supposedly secure connection between a user and, for example, an online banking site.
