FreeBSD : wine -- information disclosure due to insecure temporary file handling (48a59c96-9c6e-11d9-a040-000a95bc6fae)

Synopsis :

The remote FreeBSD host is missing a security-related update.

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's dump and get
sensitive information, like passwords and other private data.
