In this post, I’ll look at CVE-2023-6241, a vulnerability in the Arm Mali GPU that allows a malicious app to gain arbitrary kernel code execution and root on an Android phone. I’ll show how this vulnerability can be exploited even when Memory Tagging Extension (MTE), a powerful mitigation, is enabled on the device.
Learn to find and fix security issues while having fun with Secure Code Game, now with new challenges focusing on JavaScript, Python, Go, and GitHub Actions!
More developers will have to fix security issues in the age of shifting left. Here, we break down how SAST tools can help them find and address vulnerabilities.
In practice, shifting left has been more about shifting the burden rather than the ability. But AI is bringing its promise closer to reality. Here’s how.
GitHub received a bug bounty report of a vulnerability that allowed access to the environment variables of a production container. We have patched GitHub.com and rotated all affected credentials. If you have hardcoded or cached a public key owned by GitHub, read on to ensure your systems continue working with the new keys.
When socializing a new security tool, it IS possible to build a bottom-up security culture where engineering has a seat at the table. Let's explore some effective strategies witnessed by the GitHub technical sales team to make this shift successful.
This blog post describes two linked vulnerabilities found in Frigate, an AI-powered security camera manager, that could have enabled an attacker to silently gain remote code execution.
Using CVE-2023-43641 as an example, I’ll explain how to develop an exploit for a memory corruption vulnerability on Linux. The exploit has to bypass several mitigations to achieve code execution.
Learn how researchers and security experts at GitHub, Microsoft, and Santander came together to address the challenges presented by the post-quantum cryptography world.
The GitHub Security Lab examined the most popular open source software running on our home labs, with the aim of enhancing its security. Here's what we found and what you can do to better protect your own smart home.
