A critical code-execution vulnerability almost affecting everyone those are not running the most updated version of Google Android , i.e. Android version 4.4 also known as KitKat. After nine months of vulnerability disclosure to the Android security team, researchers of the Application Security team at IBM have finally revealed all the possible details of a serious code-execution vulnerability that still affects the Android devices running versions 4.3 and earlier, which could allow attackers to exfiltrate sensitive information from the vulnerable devices. " Considering Android's fragmented nature and the fact that this was a code-execution vulnerability, we decided to wait a bit with the public disclosure ," said Roee Hay, a security research group leader at IBM. The researchers found the stack buffer overflow vulnerability that resides in the Android's KeyStore storage service, which according to the Android developers' website is the service code running in Androi...

Address space layout randomization (ASLR) is a security technique involved in protection from buffer overflow attacks. Many recent APT (Advanced Persistent Threat) attacks have utilized many different ASLR bypass techniques during the past year, according to Researchers at  FireEye . Many exploits and malware attacks rely on the ability of the programmer to accurately identify where specific processes or system functions reside in memory. In order for an attacker to exploit or leverage a function, they must first be able to tell their code where to find the function or process to exploit.  The goal of ASLR  is to introduce randomness into addresses used by a given task. It involves randomly arranging the positions of key data areas of a program, including the base of the executable and the positions of the stack, heap, and libraries, in a process's address space.  Today a lot of attention is brought to client side exploits especially inside web brows...

Are you tired of dealing with outdated security tools that never seem to give you the full picture?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 ...
