Security

Open source maintainers and security researchers embrace a new best practice to report and fix vulnerabilities.

How to verifiably link npm packages to their source repository and build instructions.

In this post, I’ll look at a security-related change in version r40p0 of the Arm Mali driver that was AWOL in the January update of the Pixel bulletin, where other patches from r40p0 was applied, and how these two lines of changes can be exploited to gain arbitrary kernel code execution and root from a malicious app. This highlights how treacherous it can be when backporting security changes.

Multi-repository variant analysis lets you scale security research across thousands of repositories, giving you a powerful tool to find and respond to newly discovered vulnerabilities.

Learn how teams can leverage the power of GitHub Advanced Security’s code scanning and GitHub Actions to integrate the right security testing tools at the right time.

The GitHub Security Lab audited DataHub, an open source metadata platform, and discovered several vulnerabilities in the platform’s authentication and authorization modules. These vulnerabilities could have enabled an attacker to bypass authentication and gain access to sensitive data stored on the platform.

CVE-2022-25664, a vulnerability in the Qualcomm Adreno GPU, can be used to leak large amounts of information to a malicious Android application. Learn more about how the vulnerability can be used to leak information in both the user space and kernel space level of pages, and how the GitHub Security Lab used the kernel space information leak to construct a KASLR bypass.

Object Graph Notation Language (OGNL) is a popular, Java-based, expression language used in popular frameworks and applications, such as Apache Struts and Atlassian Confluence. Learn more about bypassing certain OGNL injection protection mechanisms including those used by Struts and Atlassian Confluence, as well as different approaches to analyzing this form of protection so you can harden similar systems.

We’re excited to share the newest addition to our GitHub Bug Bounty Program!

It turns out that the first “all Google” phone includes a non-Google bug. Learn about the details of CVE-2022-38181, a vulnerability in the Arm Mali GPU. Join me on my journey through reporting the vulnerability to the Android security team, and the exploit that used this vulnerability to gain arbitrary kernel code execution and root on a Pixel 6 from an Android app.

How Dependabot integrated with npm to address security vulnerabilities on transitive dependencies and increase the likelihood of success for JavaScript security updates by 40%.

GitHub now tells you whether GitHub tokens found by secret scanning are active so you can prioritize and escalate remediation efforts.

Dependabot is getting a little smarter—and, a little quieter—by reducing bot-based noise from repositories based on your interaction with Dependabot.

Learn about the design behind, and solutions to, several of GitHub’s CTF challenge for Ekoparty’s 2022 event!

GitHub now allows you to track any leaked secrets in your public repository, for free. With secret scanning alerts, you can track and action on leaked secrets directly within GitHub.
