cri-tools and kube-state-metrics-fips crash on Windows with null character
published 1 month ago
Summary
The Dial and LookupPort functions in cri-tools and kube-state-metrics-fips cause the program to stop unexpectedly on Windows if they receive data that includes a null (zero) character. This can interrupt the operation of containers or monitoring tools that rely on these packages. Apply the latest updates from the vendors or ensure inputs never contain a null character to prevent the crash.
