phpMyAdmin Releases Critical Software Update — Patch Your Sites Now!

December 11, 2018Mohit Kumar
Developers of phpMyAdmin, one of the most popular and widely used MySQL database management systems, today released an updated version 4.8.4 of its software to patch several important vulnerabilities that could eventually allow remote attackers to take control of the affected web servers. The phpMyAdmin project last Sunday gave an early heads-up about the latest security update through its blog, probably the first time, as an experiment to find if pre-announcements can help website admins, hosting providers and package managers better prepare for the security release. "We are inspired by the workflow of other projects (such as Mediawiki and others) which often announce any security release in advance to allow package maintainers and hosting providers to prepare. We are experimenting to see if such a workflow is suitable for our project," phpMyAdmin release manager Isaac Bennetch told The Hacker News. phpMyAdmin is a free, open-source administration tool for managing

Warning! Unprivileged Linux Users With UID > INT_MAX Can Execute Any Command

December 06, 2018Mohit Kumar
Hold tight, this may blow your mind… A low-privileged user account on most Linux operating systems with UID value anything greater than 2147483647 can execute any systemctl command unauthorizedly—thanks to a newly discovered vulnerability. The reported vulnerability actually resides in PolicyKit (also known as polkit)—an application-level toolkit for Unix-like operating systems that defines policies, handles system-wide privileges and provides a way for non-privileged processes to communicate with privileged ones, such as "sudo," that does not grant root permission to an entire process. The issue, tracked as CVE-2018-19788 , impacts PolicyKit version 0.115 which comes pre-installed on most popular Linux distributions, including Red Hat , Debian ,  Ubuntu , and CentOS. The vulnerability exists due to PolicyKit's improper validation of permission requests for any low-privileged user with UID greater than INT_MAX. Where, INT_MAX is a constant in computer progra

7 New Meltdown and Spectre-type CPU Flaws Affect Intel, AMD, ARM CPUs

November 14, 2018Swati Khandelwal
Disclosed earlier this year, potentially dangerous Meltdown and Spectre vulnerabilities that affected a large family of modern processors proven that speculative execution attacks can be exploited in a trivial way to access highly sensitive information. Since then, several more variants of speculative execution attacks have been discovered, including Spectre-NG , SpectreRSB, Spectre 1.1, Spectre1.2, TLBleed , Lazy FP , NetSpectre and Foreshadow , patches for which were released by affected vendors time-to-time. Speculative execution is a core component of modern processors design that speculatively executes instructions based on assumptions that are considered likely to be true. If the assumptions come out to be valid, the execution continues, otherwise discarded. Now, the same team of cybersecurity researchers who discovered original Meltdown and Spectre vulnerabilities have uncovered 7 new transient execution attacks affecting 3 major processor vendors—Intel, AMD, ARM.

Flaws in Popular Self-Encrypting SSDs Let Attackers Decrypt Data

November 06, 2018Swati Khandelwal
We all have something to hide, something to protect. But if you are also relying on self-encrypting drives for that, then you should read this news carefully. Security researchers have discovered multiple critical vulnerabilities in some of the popular self-encrypting solid state drives (SSD) that could allow an attacker to decrypt disk encryption and recover protected data without knowing the password for the disk. The researchers—Carlo Meijer and Bernard van Gastel—at Radboud University in the Netherlands reverse engineered the firmware several SSDs that offer hardware full-disk encryption to identify several issues and detailed their findings in a new paper ( PDF ) published Monday. "The analysis uncovers a pattern of critical issues across vendors. For multiple models, it is possible to bypass the encryption entirely, allowing for a complete recovery of the data without any knowledge of passwords or keys," the researchers say. The duo successfully tested their
