buffer overflow vulnerability | Breaking Cybersecurity News | The Hacker News

Security researchers have discovered a critical remotely exploitable vulnerability in an open-source software development library used by major manufacturers of the Internet-of-Thing devices that eventually left millions of devices vulnerable to hacking. The vulnerability (CVE-2017-9765), discovered by researchers at the IoT-focused security firm Senrio, resides in the software development library called gSOAP toolkit (Simple Object Access Protocol) — an advanced C/C++ auto-coding tool for developing XML Web services and XML application. Dubbed " Devil's Ivy ," the stack buffer overflow vulnerability allows a remote attacker to crash the SOAP WebServices daemon and could be exploited to execute arbitrary code on the vulnerable devices. The Devil's Ivy vulnerability was discovered by researchers while analysing an Internet-connected security camera manufactured by Axis Communications. "When exploited, it allows an attacker to remotely access a video ...

A critical vulnerability has been discovered in Microsoft-owned most popular free web messaging and voice calling service Skype that could allow hackers to remotely execute malicious code and crash systems. Skype is a free online service that allows users to communicate with peers by voice, video, and instant messaging over the Internet. The service was acquired by Microsoft Corporation in May 2011 for US$8.5 Billion due to its worldwide popularity. Security researcher Benjamin Kunz-Mejri from Germany-based security firm Vulnerability Lab discovered the previously unknown stack buffer overflow vulnerability, which is documented in CVE-2017-9948 , in Skype Web's messaging and call service during a team conference call. The vulnerability is considered a high-security risk with a 7.2 CVSS score and affects Skype versions 7.2, 7.35, and 7.36 on Windows XP, Windows 7 and Windows 8, Mejri said in a public security disclosure published on Monday. "The issue can be exploi...

Are you tired of dealing with outdated security tools that never seem to give you the full picture? You're not alone. Many organizations struggle with piecing together scattered information, leaving your apps vulnerable to modern threats. That's why we're excited to introduce a smarter, unified approach: Application Security Posture Management (ASPM). ASPM brings together the best of both worlds by connecting your code insights with real-time runtime data. This means you get a clear, holistic view of your application's security. Instead of reacting to threats, ASPM helps you prevent them. Imagine reducing costly retrofits and emergency patches with a proactive, shift-left strategy—saving you time, money, and stress. Join Amir Kaushansky, Director of Product Management at Palo Alto Networks, as he walks you through how ASPM is changing the game. In this free webinar , you'll learn to: Close the Security Gaps: Understand why traditional AppSec tools fall short and how ASPM fills ...

A simple but shockingly dangerous vulnerability has been uncovered in the NetUSB component, putting Millions of modern routers and other embedded devices across the globe at risk of being compromised by hackers. The security vulnerability, assigned CVE-2015-3036 , is a remotely exploitable kernel stack buffer overflow flaw resides in Taiwan-based KCodes NetUSB . NetUSB is a Linux kernel module that allows for users to flash drives, plug printers and other USB-connected devices into their routers so that they can be accessed over the local network. NetUSB component is integrated into modern routers sold by some major manufacturers including D-Link, Netgear, TP-Link, ZyXEL and TrendNet. The security flaw, reported by Stefan Viehbock of Austria-based SEC Consult Vulnerability Lab, can be triggered when a client sends the computer name to the server deployed on the networking device (TCP port 20005) in order to establish a connection. However, if a connecting comp...

The GHOST vulnerability is a buffer overflow condition that can be easily exploited locally and remotely, which makes it extremely dangerous. This vulnerability is named after the GetHOSTbyname function involved in the exploit. Attackers utilize buffer overflow vulnerabilities like this one by sending specific packets of data to a vulnerable system. The attack allows the attacker to execute arbitrary code and take control of the victim's vulnerable machine. Unfortunately, the vulnerability exists in the GNU C Library (glibc) , a code library originally released in 2000, meaning it has been widely distributed. Many derivative programs utilize the glibc to carry out common tasks. Although an update released by Linux in 2013 mitigated this vulnerability, most systems and products have not installed the patch. What Can I Do About GHOST Vulnerability? Like with any vulnerability, the best way to mitigate GHOST vulnerability is to identify vulnerable systems, prioritiz...
