WordPress patches dangerous XSS, SQL injection bugs

By -
Summary: The security release fixes three flaws in the content management system.
WordPress has patched three security flaws including a cross-site scripting (XSS) vulnerability and SQL injection problem which could lead to the creation of new vulnerabilities.
The first bug, reported by David Herrera of Alley Interactive, is an information disclosure vulnerability which reveals the user interface for assigning taxonomy terms in the "Press This" function -- used to publish posts through browsers -- to users that do not have permission to see it.Last week, the content management system's (CMS) developers said in a security advisory that the new fixes resolve three important security issues, all of which impact WordPress versions 4.7.1 and earlier.
The second issue was discovered in the WP_Query process, used to access variables and functions in the WordPress core, by researcher Mo Jangda. When passing data seemed "unsafe," the system became vulnerable to SQL injection attacks.
While the WordPress core was not directly vulnerable due to the security flaw, the team said the patch adds hardening which will "prevent plugins and themes from accidentally causing a vulnerability."
Another newly-discovered flaw was an XSS vulnerability, discovered and reported by a member of the internal WordPress team in the CMS' posts list table class.
The latest WordPress security update has been pushed out only two weeks after the team released WordPress version 4.7.1, which fixed a total of eight problems that could lead to remote attacks, including cross-site scripting bugs, a remote code execution (RCE) bug in PHPMailer, information leaks, and a cross-site request forgery (CSRF) flaw.
WordPress users can download the latest 4.7.2. version manually or click the "Update Now" button on the CMS dashboard for the update to download. Automatic updates are now being rolled out to websites which support this feature.

It finally happened. Today, all 500 of the world's top 500 supercomputers are running Linux. Linux rules supercomputing. This day has been coming since 1998, when Linux first appeared on the TOP500 Supercomputer list . Today it finally happened:  All 500 of the world's fastest supercomputers are running Linux . The last two non-Linux systems, a pair of Chinese IBM POWER computers running AIX, dropped off the  November 2017 TOP500 Supercomputer list . Overall, China now leads the supercomputing race with 202 computers to the US' 144. China also leads the US in aggregate performance. China's supercomputers represent 35.4 percent of the Top500's flops, while the US trails with 29.6 percent. With an anti-science regime in charge of the government, America will only continue to see its technological lead decline. When the  first Top500 supercomputer list was compiled in June 1993 , Linux was barely more than a toy. It hadn't even adopted Tux as its masc

Microsoft tries to stem its self-made collaboration-tool confusion

Microsoft is using this week's Ignite conference to try to help clarify its collaboration-tool strategy. Here's how SharePoint, Teams and Yammer figure in the mix. Choice is good. But too much choice, especially when it comes to collaboration tools, has been a problem for Microsoft. This isn't news to customers, partners or Microsoft execs themselves. But at the company's Ignite IT Pro conference in Orlando this week, Microsoft execs took a step to try to clarify the company's strategy and messaging in this area. Microsoft Office 365 Marketing chief Ron Markezich kicked off the conference this week with a slide entitled "Microsoft 365 Teamwork: Where to Start a Conversation." That slide attempts to do what  Microsoft initially attempted with a 60-plus-page whitepaper : Clarify which collaboration tools customers should use when. The slide, which features SharePoint -- and its files, sites and content storage at the center -- is broken down into t
