Information Exposure in RunC

Quick fix

GHSA-gp4j-w3vj-7299 — github.com/opencontainers/runc: upgrade to the fixed version with the command below.

go get github.com/opencontainers/runc@v1.0.0-rc3

Details

RunC allowed additional container processes via 'runc exec' to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container.
