Due to insecure temporary file creation in the Wine Windows
emulator, it is possible for any user to read potentially
sensitive information from temporary registry files.
When a Win32 application is launched by wine, wine makes
a dump of the Windows registry in /tmp with name
regxxxxyyyy.tmp , where xxxxxx is the pid in hexadecimal
value of the current wine process and yyyy is an integer
value usually equal to zero.
regxxxxyyyy.tmp is created with 0644 (-rw-r–r–)
permissions. This could represent a security problem in a
multi-user environment. Indeed, any local user could
access to windows regstry’s dump and get sensitive
information, like passwords and other private data.
