Billions of Android Devices Vulnerable to Privilege Escalation Except Android 5.0 Lollipop

Billions of Android Devices Vulnerable to Privilege Escalation Except Android 5.0 Lollipop

Nov 20, 2014
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 p...
Android 4.3 and Earlier versions Vulnerable to Critical Code-Execution Flaw

Android 4.3 and Earlier versions Vulnerable to Critical Code-Execution Flaw

Jun 27, 2014
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...
How AI Is Transforming IAM and Identity Security

How AI Is Transforming IAM and Identity Security

Nov 15, 2024Machine Learning / Identity Security
In recent years, artificial intelligence (AI) has begun revolutionizing Identity Access Management (IAM), reshaping how cybersecurity is approached in this crucial field. Leveraging AI in IAM is about tapping into its analytical capabilities to monitor access patterns and identify anomalies that could signal a potential security breach. The focus has expanded beyond merely managing human identities — now, autonomous systems, APIs, and connected devices also fall within the realm of AI-driven IAM, creating a dynamic security ecosystem that adapts and evolves in response to sophisticated cyber threats. The Role of AI and Machine Learning in IAM AI and machine learning (ML) are creating a more robust, proactive IAM system that continuously learns from the environment to enhance security. Let's explore how AI impacts key IAM components: Intelligent Monitoring and Anomaly Detection AI enables continuous monitoring of both human and non-human identities , including APIs, service acc...
Critical GnuTLS Flaw Leaves SSL Clients Vulnerable to Remote Code Execution

Critical GnuTLS Flaw Leaves SSL Clients Vulnerable to Remote Code Execution

Jun 04, 2014
GnuTLS, a widely used open source SSL/TLS cryptographic library is vulnerable to a buffer overflow vulnerability that could be exploited to crash TLS clients or potentially execute malicious code on underlying systems. The GnuTLS library implements secure sockets layer (SSL) and transport layer security (TLS) protocols on computers, servers, and softwares to provide encrypted communications over insecure channels. The bug ( CVE-2014-3466 ) was independently discovered by Joonas Kuorilehto of security firm Codenomicon, the same security firm who discovered the biggest Internet vulnerability, Heartbleed. Unlike Heartbleed, the GnuTLS library is not as widely deployed as OpenSSL. The GnuTLS Vulnerability resides in the way GnuTLS parses the session ID from the server response during a TLS handshake. It does not check the length of session ID value in the ServerHello message, which allows a malicious server to send an excessively long value in order to execute buffer overf...

A new class of identities has emerged alongside traditional human users: non-human identities (NHIs). Permiso Security's new eBook details everything you need to know about managing and securing non-human identities, and strategies to unify identity security without compromising agility.
23-year-old Stack overflow vulnerability discovered in X11 Server

23-year-old Stack overflow vulnerability discovered in X11 Server

Jan 09, 2014
X.Org Foundation develops the X-Window System, the standard window system for open source operating systems and devices. Most of the graphical user interfaces for Unix and Linux systems rely on it. At the 30th Chaos Communication Congress (CCC) in Germany, Ilja van Sprundel , a security researcher gave the presentation titled  " X11 Server security with being 'worse than it looks.'". He found more than 120 bugs in a few months. In the presentation, he has presented a 23 year old Stack overflow vulnerability in X11 System that could lead to privilege escalation to root and affects all versions of the X Server back to X11R5. Later today, X.Org Foundation released a security Advisory , states " A BDF font file containing a longer than expected string could overflow the buffer on the stack. Testing in X servers built with Stack Protector resulted in an immediate crash when reading a user-provided specially crafted font. " The flaw resides in a file at " libXfo...
Windows Error Crash Reports or Treasure of Zero-Day vulnerabilities for NSA?

Windows Error Crash Reports or Treasure of Zero-Day vulnerabilities for NSA?

Jan 03, 2014
I am sure that you all have been familiar with the above shown annoying Window Operating System error messages that many times pop ups on your screen while working on the system in case of process failure i.e. " The system has recovered from a serious error. A log of this error has been created. Please tell Microsoft about this problem " The message that prompts ask the user to report the problem to Microsoft followed by the options to Send an error report or Not send . Most of the time Gentle users like you and me used to submit these error reports to aware the Microsoft about the problem. But What if these crash reports can be abused to identify the vulnerabilities of your system for Spying? NSA is intercepting wide range of Internet Traffic including many Encrypted connections and naturally unencrypted also and surprisingly, by default Microsoft encrypts its reports, but the messages are transmitted unencrypted or over standard HTTP connections to watson.microsoft.c...
Buffer Overflow vulnerability in VLC media player

Buffer Overflow vulnerability in VLC media player

Feb 01, 2013
VideoLAN recently published a security advisory warning of a buffer overflow vulnerability in versions 2.0.5 and earlier of VLC Media Player, which might be exploited to execute arbitrary code. This vulnerability was reported by Debasish Mandal. The vulnerability is caused due to an error in the "DemuxPacket()" function (modules/demux/asf/asf.c) when processing ASF files and can be exploited to cause a buffer overflow via a specially crafted ASF file. To exploit the vulnerability, a user must explicitly open a specially crafted ASF movie. Successful exploitation may allow execution of arbitrary code, but requires tricking a user into opening a malicious file. VideoLAN advises users to refrain from opening files from untrusted locations and to disable the VLC browser plug-ins until the issue is patched. A patch will be included in VLC 2.0.6, the next version of the media player, which is only available for testing purposes at the moment.
