Important: runc security update (Amazon Linux 2023)

Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2024-21626: AWS is aware of CVE-2024-21626, an issue affecting the runc component of several open source container management systems. Under certain conditions, an actor could leverage a specially crafted container or container configuration to access files or directories outside the container's file system namespace. An updated version of runc that addresses the issue is available for Amazon Linux 1 (runc-1.1.11-1.0.amzn1), Amazon Linux 2 (runc-1.1.11-1.amzn2) and for Amazon Linux 2023 (runc-1.1.11-1.amzn2023). AWS recommends that customers using runc or any container-related software apply those updates or a newer version. CVE-2023-39326: A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small.
