Summary

Privilege escalation in github.com/opencontainers/runc

Details

GetExecUser in the github.com/opencontainers/runc/libcontainer/user package will improperly interpret numeric UIDs as usernames. If the method is used without verifying that usernames are formatted as expected, it may allow a user to gain unexpected privileges.
