FreeBSD : wine -- information disclosure due to insecure temporary file handling (48a59c96-9c6e-11d9-a040-000a95bc6fae)
Low Nessus Plugin ID 18924
The remote FreeBSD host is missing a security-related update.
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.
