Ludovic Courtès reports:

The REPL server is vulnerable to the HTTP inter-protocol attack

The ‘mkdir’ procedure of GNU Guile, an implementation of the Scheme programming language, temporarily changed the process’ umask to zero. During that time window, in a multithreaded application, other threads could end up creating files with insecure permissions.
