Bypass ASLR | Breaking Cybersecurity News | The Hacker News

Security researchers have discovered not one or two, but a total of seven security vulnerabilities in the popular open source Dnsmasq network services software, three of which could allow remote code execution on a vulnerable system and hijack it. Dnsmasq is a widely used lightweight network application tool designed to provide DNS (Domain Name System) forwarder, DHCP (Dynamic Host Configuration Protocol) server, router ads and network boot services for small networks. Dnsmasq comes pre-installed on various devices and operating systems, including Linux distributions such as Ubuntu and Debian, home routers, smartphones and Internet of Things (IoT) devices. A shodan scan for "Dnsmasq" reveals around 1.1 million instances worldwide. Recently, Google's security team reviewed Dnsmasq and discovered seven security issues, including DNS-related remote code execution, information disclosure, and denial-of-service (DoS) issues that can be triggered via DNS or DHCP. &q

Security researchers have discovered a chip flaw that could nullify hacking protections for millions of devices regardless of their operating system or application running on them, and the worse — the flaw can not be entirely fixed with any mere software update. The vulnerability resides in the way the memory management unit (MMU), a component of many CPUs, works and leads to bypass the Address Space Layout Randomization (ASLR) protection. ASLR is a crucial security defense deployed by all modern operating systems from Windows and Linux to macOS, Android, and the BSDs. In general, ASLR is a memory protection mechanism which randomizes the location where programs run in a device's memory. This, in turn, makes it difficult for attackers to execute malicious payloads in specific spots in memory when exploiting buffer overflows or similar bugs. In short, for attackers, it's like an attempt to burglarize a house blindfolded. But now a group of researchers, known as VUSe

Designed to be more than a one-time assessment— Wing Security's SaaS Pulse provides organizations with actionable insights and continuous oversight into their SaaS security posture—and it's free! Introducing SaaS Pulse: Free Continuous SaaS Risk Management  Just like waiting for a medical issue to become critical before seeing a doctor, organizations can't afford to overlook the constantly evolving risks in their SaaS ecosystems. New SaaS apps, shifting permissions, and emerging threats mean risks are always in motion. SaaS Pulse makes it easy to treat SaaS risk management as an ongoing practice, not just an occasional check-up. Security teams instantly get a real-time security "health" score, prioritized risks, contextualized threat insights, and the organization's app inventory—without setups or integrations. SaaS is a Moving Target SaaS stacks don't stand still. Business critical apps can easily slip into a state of vulnerability (i.e. supply chain attacks, account takeovers

A security weakness in Android mobile operating system versions below 5.0 that puts potentially every Android device at risk for privilege escalation attacks, has been patched in  Android 5.0 Lollipop  – the latest version of the mobile operating system. The security vulnerability ( CVE-2014-7911 ), discovered by a security researcher named Jann Horn , could allow any potential attacker to bypass the Address Space Layout Randomization (ASLR) defense and execute arbitrary code of their choice on a target device under certain circumstances. ASLR is a technique involved in protection from buffer overflow attacks. The flaw resides in java.io.ObjectInputStream , which fails to check whether an Object that is being deserialized is actually a serializable object. The vulnerability was reported by the researcher to Google security team earlier this year. According to the security researcher, android apps can communicate with system_service, which runs under admin privileges
