Official description

DIRAC is an interware, meaning a software framework for distributed computing. Prior to version 8.0.41, during the proxy generation process (e.g., when using `dirac-proxy-init`), it is possible for unauthorized users on the same machine to gain read access to the proxy. This allows the user to then perform any action that is possible with the original proxy. This vulnerability only exists for a short period of time (sub-millsecond) during the generation process. Version 8.0.41 contains a patch for the issue. As a workaround, setting the `X509_USER_PROXY` environment variable to a path that is inside a directory that is only readable to the current user avoids the potential risk. After the file has been written, it can be safely copied to the standard location (`/tmp/x509up_uNNNN`).
