Vulnerabilities in software from Schneider Electric

I found multiple vulnerabilities in software from Schneider Electric, used to monitor industrial monitoring devices. It reveals a very poor security design. The editor was informed and I am waiting for its acknowledgement. I will disclose more details once the issues are patched.

SecurityFocus changing

A big change on Security Focus is going to happen. Except the vulnerability database, most of its content and resources are going to move to Symantec. RIP.

Nessus 4.2

Nessus 4.2 is out. I tried it out and I must say that the new UI is great. I am not a big fan of Flash and I regret this choice. However, the design is excellent, all options are accessible in a logical way. Instead of spreading over the options like it used to be, [...]

It is vulnerable to a MiTM attack where the attacker can intercept and retrieve the credential to a trusted HTTPS website, by intercepting the session cookie sent back to the client. A proof of concept of an attack against Twitter was [...]

The threat is serious as it could allow a local user to gain root privileges. Those who compile their own 2.6.x kernel should apply this patch (from Linus, check there [...]

I see many people making a confusion about the use of this term, even among professional or specialized journalists. Whenever there is a hack originated from the Internet, they call it a [...]

The SSL/SSH disaster

Due to the recent security hole discovered in Debian, which has also concerned various distributions – of course including Ubuntu – for 2 years, I simply closed all my SSH and OpenVPN accesses. I have had no time so far to check all the keys on my server. I prefer to stay on the safe [...]

Cold boot attack, not a threat to Full disk encryption (FDE)

Since the new cold boot attack hack is on the news, touching most of the software encryption solutions, I have wondered if it had any chance to concern also hardware encryption. Hardware encryption is provided by a few laptop makers, generally on high-range an business models. It has much less performance impact than software encryption, [...]
