Dist Fedora Esm H88
A recent patch for Fedora 39 targets vulnerabilities found in Firecracker, caused by vm-memory v0.12.2, which poses risks for serverless infrastructures.
Rebuild dependent packages for vm-memory v0.12.2 to address CVE-2023-41051 / RUSTSEC-2023-0056

Summary

Firecracker is an open source virtualization technology that is purpose-built

for creating and managing secure, multi-tenant container and function-based

services that provide serverless operational models. Firecracker runs

workloads in lightweight virtual machines, called microVMs, which combine the

security and isolation properties provided by hardware virtualization

technology with the speed and flexibility of containers.

This package does not include all of the security features of an official

release. It is not production ready without additional sandboxing.
