Description Adam Mariš 2016-02-29 16:00:33 UTC 
It was reported that wine uses /tmp/.wine-$UID as a directory for sockets and lock files. Malicious local user could create /tmp/.wine-$UID for another user's uid, preventing the other user from using wine. Moreover, the server_connect() function doesn't check if /tmp/.wine-$UID or its subdirectories are symlinks, so in some circumstances it might be possible to trick wine to connect to an unrelated socket.
