New Systemd Privilege Escalation Flaws Affect Most Linux Distributions

New Systemd Privilege Escalation Flaws Affect Most Linux Distributions

Jan 10, 2019
Security researchers have discovered three vulnerabilities in Systemd, a popular init system and service manager for most Linux operating systems, that could allow unprivileged local attackers or malicious programs to gain root access on the targeted systems. The vulnerabilities, assigned as CVE-2018-16864, CVE-2018-16865, and CVE-2018-16866, actually resides in the "systemd-journald" service that collects information from different sources and creates event logs by logging information in the journal. The vulnerabilities, which were discovered and reported by security researchers at Qualys, affect all systemd-based Linux distributions, including Redhat and Debian , according to the researchers. However, some Linux distros such as SUSE Linux Enterprise 15, openSUSE Leap 15.0, and Fedora 28 and 29 are not affected, as "their userspace [code] is compiled with GCC's -fstack-clash-protection ." The first two flaws are memory corruptions issues, while the

New Privilege Escalation Flaw Affects Most Linux Distributions

Oct 26, 2018
An Indian security researcher has discovered a highly critical flaw in X.Org Server package that impacts OpenBSD and most Linux distributions, including Debian, Ubuntu, CentOS, Red Hat, and Fedora. Xorg X server is a popular open-source implementation of the X11 system (display server) that offers a graphical environment to a wider range of hardware and OS platforms. It serves as an intermediary between client and user applications to manage graphical displays. According to a blog post published by software security engineer Narendra Shinde , Xorg X server doesn't correctly handle and validate arguments for at least two command-line parameters, allowing a low-privileged user to execute malicious code and overwrite any file—including files owned by privileged users like root. The flaw, tracked as CVE-2018-14665 , was introduced in X.Org server 1.19.0 package that remained undetected for almost two years and could have been exploited by a local attacker on the terminal or vi
Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Apr 15, 2024Active Directory / Attack Surface
To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning
Malicious Software Packages Found On Arch Linux User Repository

Malicious Software Packages Found On Arch Linux User Repository

Jul 11, 2018
Yet another incident which showcases that you should not explicitly trust user-controlled software repositories. One of the most popular Linux distros Arch Linux has pulled as many as three user-maintained software repository AUR packages after it was found hosting malicious code. Arch Linux is an independently developed, general-purpose GNU/Linux distribution composed predominantly of free and open-source software, and supports community involvement. Besides official repositories like Arch Build System (ABS), Arch Linux users can also download software packages from several other repositories, including AUR (Arch User Repository), a community-driven repository created and managed by Arch Linux users. Since AUR packages are user-produced content, Arch maintainers always suggest Linux users to carefully check all files, especially PKGBUILD and any .install file for malicious commands. However, this AUR repository has recently been found hosting malware code in several inst

SUSE Linux Has Been Sold For $2.5 Billion

SUSE Linux Has Been Sold For $2.5 Billion

Jul 03, 2018
SUSE, the open source software company owned by British firm Micro Focus International, has been sold to a Swedish private equity firm. Yes, SUSE Linux and its associated software business has finally been acquired by EQT Partners for $2.535 billion, lifting its shares 6 percent. SUSE is one of the oldest open source companies and perhaps the first to provide enterprise-grade Linux software service to banks, universities and government agencies around the world. Since its foundation in 1992, SUSE has changed ownership multiple times. US-based software company Novell acquired SUSE for $120 million in November 2003 to compete with Microsoft in the operating system market. However, things did not work as the company thought and Novell in turn itself was acquired by another US-based company The Attachmate Group for $2.2 billion in 2011. Three years later, Micro Focus International acquired Attachmate for $2.35 billion in 2014. Since then SUSE Linux has been part of Micro Focus
Microsoft has Built its own Linux Operating System

Microsoft has Built its own Linux Operating System

Sit Tight on your seats, because you're gonna get a Shock. Microsoft has developed an Operating System powered by LINUX. Close your mouth first. It's True! Microsoft has built its own Linux-based operating system called Azure Cloud Switch (ACS ) and believe me, under Satya Nadella, Microsoft has become more open than ever. According to the announcement made through an official blog post on Microsoft website, Azure Cloud Switch (ACS) describes as "cross-platform modular operating system for data center networking built on Linux." or Simply, " Commodity switch software stack for data center networks". The Purpose of developing Linux-based Azure Cloud Switch (ACS) operating system at Microsoft is to make it simpler to control the hardware from multiple vendors ( such as Switches ) that powers their cloud-based services. And here's the Kicker: "Running on Linux, ACS [Azure Cloud Switch] is able to make use of its vibrant eco
