On September 16, GitHub Security learned that threat actors were targeting GitHub users with a phishing campaign by impersonating CircleCI to harvest user credentials and two-factor codes. While GitHub itself was not affected, the campaign has impacted many victim organizations.
Dependabot alerts can give you the ability to secure your project by keeping dependency-based vulnerabilities out of your code. Here are some tips to more efficiently prioritize and take action on your alerts, so you can get back to building.
We’re taking a look at two commonly-used security tools and detailing how they can help secure your projects.
GitHub Actions gives teams access to powerful, native CI/CD capabilities right next to their code hosted in GitHub. Starting today, GitHub will send a Dependabot alert for vulnerable GitHub Actions, making it even easier to stay up to date and fix security vulnerabilities in your actions workflows.
Supply chain attacks exploit our implicit trust of open source to hurt developers and our customers. Read our proposal for how npm will significantly reduce supply chain attacks by signing packages with Sigstore.
Today, we’re expanding access to the GitHub security overview! All GitHub Enterprise customers now have access to the security overview, not just those with GitHub Advanced Security. Additionally, all users within an enterprise can now access the security overview, not just admins and security managers.
In this post I’ll exploit CVE-2022-20186, a vulnerability in the Arm Mali GPU kernel driver and use it to gain arbitrary kernel memory access from an untrusted app on a Pixel 6. This then allows me to gain root and disable SELinux. This vulnerability highlights the strong primitives that an attacker may gain by exploiting errors in the memory management code of GPU drivers.
New npm security enhancements include an improved login and publish experience with the npm CLI, connected GitHub and Twitter accounts, and a new CLI command to verify the integrity of packages in npm.
New Actions from Anchore, NowSecure, SBT, and Trivy are now available to create a more comprehensive GitHub Dependency Graph.
Can projects and GitHub Actions be used by your non-developer teams? They absolutely can. Check out how our Security Team uses GitHub to run the department effortlessly.
In this post I'll exploit CVE-2022-1134, a type confusion in Chrome that I reported in March 2022, which allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site. I'll also look at some past vulnerabilities of this type and some implementation details of inline cache in V8, the JavaScript engine of Chrome.
The recent changes to improve protocol security on GitHub.com are now coming to GitHub Enterprise Server, starting with version 3.6.
We’re excited to announce that the GitHub Advisory Database now includes curated security advisories on Erlang, Elixir, and more.
GitHub is excited to announce the release of CodeQL queries that implement the standards CERT C++ and AUTOSAR C++. These queries can aid developers looking to demonstrate ISO 26262 Part 6 process compliance.
Expand the completeness of your dependency graph by using the dependency submission API, which will create more comprehensive alerts on supply chain vulnerabilities
In this post I’ll exploit CVE-2022-22057, a use-after-free in the Qualcomm gpu kernel driver, to gain root and disable SELinux from the untrusted app sandbox on a Samsung Z flip 3. I’ll look at various mitigations that are implemented on modern Android devices and how they affect the exploit.
