Description

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
