IBM Buys "Red Hat" Open-Source Software Company for $34 Billion

IBM Buys "Red Hat" Open-Source Software Company for $34 Billion

Oct 29, 2018
It's been quite a year for the open source platforms. Earlier this year, Microsoft acquired popular code repository hosting service GitHub for $7.5 billion , and now IBM has just announced the biggest open-source business deal ever. IBM today confirmed that it would be acquiring open source Linux firm Red Hat for $190 per share in cash, working out to a total value of approximately $34 billion. Red Hat, known for its Red Hat Enterprise Linux (RHEL) operating system, is a leading software company that offers open-source software products to the enterprise community. Even Oracle uses Red Hat's source code for its Oracle Linux product. Red Hat's last year revenue was $2.4 billion, and this year the company has earned $2.9 billion. But if Red Hat products are open source and updates are free, you might be wondering how does the company earn. Red Hat was one of the first companies who found a successful way to make money from free open-source software. It offers consul...
Google Hacker Discloses New Linux Kernel Vulnerability and PoC Exploit

Google Hacker Discloses New Linux Kernel Vulnerability and PoC Exploit

Sep 28, 2018
A cybersecurity researcher with Google Project Zero has released the details, and a proof-of-concept (PoC) exploit for a high severity vulnerability that exists in Linux kernel since kernel version 3.16 through 4.18.8. Discovered by white hat hacker Jann Horn, the kernel vulnerability (CVE-2018-17182) is a cache invalidation bug in the Linux memory management subsystem that leads to use-after-free vulnerability, which if exploited, could allow an attacker to gain root privileges on the targeted system. The use-after-free (UAF) vulnerabilities are a class of memory corruption bug that can be exploited by unprivileged users to corrupt or alter data in memory, enabling them to cause a denial of service (system crash) or escalate privileges to gain administrative access on a system. Linux Kernel Exploit Takes an Hour to Gain Root Access However, Horn says his PoC Linux kernel exploit made available to the public "takes about an hour to run before popping a root shell....
5 Reasons Device Management Isn't Device Trust​

5 Reasons Device Management Isn't Device Trust​

Apr 21, 2025Endpoint Security / Zero Trust
The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
Red Hat Linux DHCP Client Found Vulnerable to Command Injection Attacks

Red Hat Linux DHCP Client Found Vulnerable to Command Injection Attacks

May 15, 2018
A Google security researcher has discovered a critical remote command injection vulnerability in the DHCP client implementation of Red Hat Linux and its derivatives like Fedora operating system. The vulnerability, tracked as CVE-2018-1111 , could allow attackers to execute arbitrary commands with root privileges on targeted systems. Whenever your system joins a network, it's the DHCP client application which allows your system to automatically receive network configuration parameters, such as an IP address and DNS servers, from the DHCP (Dynamic Host Control Protocol) server. The vulnerability resides in the NetworkManager integration script included in the DHCP client packages which is configured to obtain network configuration using the DHCP protocol. Felix Wilhelm from the Google security team found that attackers with a malicious DHCP server, or connected to the same network as the victim, can exploit this flaw by spoofing DHCP responses, eventually allowing them to run...
