activesupport is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework.
Affected versions of this package are vulnerable to Information Exposure. The ImpactActiveSupport::EncryptedFile
method writes contents that will be encrypted to a temporary file. The temporary file’s permissions are defaulted to the user’s current umask settings, meaning that it’s possible for other users on the same system to read the contents of the temporary file.
Note:
Attackers that have access to the file system could possibly read the contents of this temporary file while a user is editing it.
Users can set the umask to be more restrictive: ruby$ umask 0077
