Overview
github.com/opencontainers/runc/libcontainer is a package for a modern container runtime.
Affected versions of this package are vulnerable to Buffer Overflow when writing netlink
messages. It is possible to have a byte array larger than UINT16_MAX
which would result in the length field overflowing and allowing user-controlled data to be parsed as control characters.
