Name of the Vulnerable Software and Affected Versions GNU Guile versions prior to 2.0.13

Description The issue arises from the mkdir procedure in GNU Guile, which temporarily changes the process' umask to zero. In a multithreaded application, this time window allows other threads to create files with insecure permissions. For instance, using mkdir without specifying the mode argument results in directories being created with 0777 permissions.

Recommendations For versions prior to 2.0.13, update to Guile 2.0.13 to resolve the issue.
