Disclosed earlier this year, potentially dangerous Meltdown and Spectre vulnerabilities that affected a large family of modern processors proven that speculative execution attacks can be exploited in a trivial way to access highly sensitive information. Since then, several more variants of speculative execution attacks have been discovered, including Spectre-NG , SpectreRSB, Spectre 1.1, Spectre1.2, TLBleed , Lazy FP , NetSpectre and Foreshadow , patches for which were released by affected vendors time-to-time. Speculative execution is a core component of modern processors design that speculatively executes instructions based on assumptions that are considered likely to be true. If the assumptions come out to be valid, the execution continues, otherwise discarded. Now, the same team of cybersecurity researchers who discovered original Meltdown and Spectre vulnerabilities have uncovered 7 new transient execution attacks affecting 3 major processor vendors—Intel, AMD, ARM. W...

A new exploit for IE9 bypasses all security measures in even the latest fully patched version of Windows 7, according to a French security company Vupen. The exploit uses an unpatched zero-day vulnerability in Internet Explorer 9 and bypasses all the extra security measures of Windows 7. The latest version of Microsoft's operating system, fully up-to-date with service pack 1 (SP1), is vulnerable. The security hole was reported by the French security company Vupen, that previously discovered an IE8 vulnerability in December of last year. Vupen classifies the exploit for IE9 as reliable, which means it's an effective way for cyber attackers to run malicious code of their choosing on Windows 7 PCs. The exploit manages to break through Windows' additional security layers, such as ASLR, DEP and the sandbox (Protected Mode) in IE9. "The exploit uses two distinct vulnerabilities. The first one allows execution of arbitrary code within the IE9 sandbox. The second one allo...

Just yesterday, I wrote a warning article announcing that Drupal – the popular open source content management system – will release patches for several highly critical Remote Code Execution (RCE) bugs that could allow attackers to fully take over any affected site. Below are the three separate Drupal modules that affect up to 10,000 websites: 1. RESTful Web Services – a popular module used for creating REST APIs, which is currently installed on at least 5,804 websites. The vulnerability in RESTWS alters the default page callbacks for entities to provide additional functionality, allowing attackers to "send specially crafted requests resulting in arbitrary PHP execution." Since anonymous users can exploit this vulnerability and there isn't any mitigating factor, users are advised to patch their websites as soon as possible. Admins using RESTful Web Services versions 7.x-2.x prior to 7.x-2.6 and versions 7.x-1.x prior to 7.x-1.7 for their Drupal websites are...
