Researchers have discovered a severe memory corruption vulnerability inside of a cloud logging utility used across major cloud platforms.

The service, Fluent Bit, is an open source tool for collecting, processing, and forwarding logs and other types of application data. It's one of the more popular pieces of software out there, with more than 3 billion downloads as of 2022, and a new 10 million or so deployments with each passing day. It's used by major organizations such as VMware, Cisco, Adobe, Walmart, and LinkedIn, and nearly every major cloud service provider, including AWS, Microsoft, and Google Cloud.
