Security

Recently, the Copyright Office responded to the calls to clarify the scope of protected security research.

In this post, I’ll use three bugs that I reported to Qualcomm in the NPU (neural processing unit) driver to gain arbitrary kernel code execution as root user and disable SELinux from the untrusted app sandbox in an Android phone.

The Exiv2 team tightened our security by enabling GitHub’s code scanning feature and adding custom queries tailored to the Exiv2 code base.

This blog post is the first in a series about hardening the security of the Exiv2 project. My goal is to share tips that will help you harden the security of your own project.

This post is a technical analysis of a recently disclosed Chrome vulnerability in the garbage collector of v8 (CVE-2021-37975) that was believed to be exploited in the wild. This vulnerability was reported by an anonymous researcher and was patched on September 30, 2021 in Chrome version 94.0.4606.71. I’ll cover the root cause analysis of the bug, as well as detailed exploitation.

On September 28, 2021, we received notice from the developer Axosoft regarding a vulnerability in a dependency of their popular git GUI client – GitKraken. An underlying issue with a dependency, called `keypair`, resulted in the GitKraken client generating weak SSH keys.

Today, we’re adding a proxy on top of the GitHub Advisory Database that speaks the `npm audit` protocol. This means that every version of the npm CLI that supports security audits is now talking directly to the GitHub Advisory Database.

GitHub’s bug bounty team is excited to kick off Cybersecurity Awareness Month with a spotlight on two security researchers who participate in the GitHub Security Bug Bounty Program.

In this post, I’ll exploit a use-after-free (CVE-2021-30528) in the Chrome browser process that I reported to escape the Chrome sandbox. This is a fairly interesting bug that shows some of the subtleties involved in the interactions between C++ and Java in the Android version of Chrome.

This post is a technical analysis of a recently disclosed Chrome JIT vulnerability (CVE-2021-30632) that was believed to be exploited in the wild. This vulnerability was reported by an anonymous researcher and was patched on September 13, 2021 in Chrome version 93.0.4577.82. I’ll cover the root cause analysis of the bug, as well as detailed exploitation.

npm access tokens will now follow the established format of GitHub authentication tokens.

We’re excited to announce that the GitHub Advisory Database now includes curated security advisories on the Rust ecosystem!

During an audit of Apache Dubbo v2.7.8 source code, I found multiple vulnerabilities enabling attackers to compromise and run arbitrary system commands on both Dubbo consumers and providers. In this blog post I detailed how I leveraged CodeQL as an audit oracle to help me find these issues.

We put out a call to open source developers and security researchers to talk about the security vulnerability disclosure process. Here’s what we found.

Between July 21, 2021 and August 13, 2021 we received reports through one of our private security bug bounty programs from researchers regarding vulnerabilities in tar and @npmcli/arborist.
