Information Disclosure

github.com/opencontainers/runc is vulnerable to information disclosure attacks. These attacks are possible because a run exec command can be ptraced by the pid 1 of the container. Using this, it allows attackers to gain access to the file-descriptors of new processes during initialization. It may...
