Google Search Console fail over notifications for the WordPress updates

I have quite a lot of WordPress based websites which I run and maintain. One of these is this blog: www.SorinMustaca.com All my WordPress websites are configured to autoupdate to the latest WordPress update. The same applies to their plugins and themes. Google Search Console (GSC) is a tool I used to manage better the registration of my websites with the search engine and their advertising platform Adsense. Yesterday evening I received a couple of emails, one for each of my websites registered with the GSC : Here is the text: Recommended WordPress update available for http://sorinmustaca.com/ To: Webmaster of http://sorinmustaca.com/, Google has detected that your site is currently running WordPress 4.7.0 or 4.7.1, an older version of WordPress. Outdated or unpatched software can be vulnerable to hacking and malware exploits that harm potential visitors to your site. Therefore, we suggest you update the software on your site as soon as possible. Following are one or more example URLs where we found pages that have outdated software.

WinRAR: The wrong way of answering to a critical vulnerability

With over 500 million users worldwide, WinRAR is by far the most popular compression program. An independent security lab found a remote code execution vulnerability in the official WInRAR SFX v5.21 software. The vulnerability allows remote attackers to unauthorized execute system specific code to compromise a target system. The issue is located in the Text and Icon function of the Text to display in SFX window module.  Remote attackers are able to generate own compressed archives with malicious payloads to execute system specific codes for compromise. The security risk of the code execution vulnerability is estimated as critical with a CVSS(common vulnerability scoring system) count of 9.2. Exploitation of the code execution vulnerability requires low user interaction (open file) without privilege system or restricted user accounts. Successful exploitation of the remote code execution vulnerability in the WinRAR SFX software results in system, network or device compromise. Simple words: Basically, the attack uses the option to write HTML code in the text display window when creating a SFX archive.   ZDNet contacted the creators of the software, Rar Labs and the answer left me baffled when they explained ZDNet that as SFX archives can run contained executable files — and is required by installers —…

The mysterious OpenSSL vulnerability has been patched

No, it doesn’t have a name like Heartbleed or POODLE, it was “just” a denial-of-service. “Just” is by no means something to be ignored, but it is less dangerous with the previous vulnerabilities. All users of OpenSSL 1.0.2 should upgrade immediately to version 1.0.2a. In the advisory published on their website the OpenSSL vulnerability is called “ClientHello sigalgs DoS (CVE-2015-0291)”. If a client connects to an OpenSSL 1.0.2 server and renegotiates with an invalid signature algorithms extension, a NULL pointer dereference will occur. This can be exploited in a DoS attack against the server. According to OpenSSL’s Security Policy, a “high severity issue”  includes issues affecting common configurations which are also likely to be exploitable. Examples include a server DoS (like this one), a significant leak of server memory (Heartbleed), and remote code execution. OpenSSL promises that such issues “will be kept private and will trigger a new release of all supported versions”. They will attempt to keep the time these issues are private to a minimum, but the goal would be “no longer than a month” where this is something that can be controlled, and significantly quicker if there is a significant risk or we are aware the issue is…
