Summary: Can escape to / directory. Causes crash Product: Wine Version: 20050930 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: wine-binary AssignedTo: wine-bugs@winehq.org ReportedBy: pdevries@ebw-electronics.com
Wine can "escape" to the OS directory structure. Sometimes, this causes a crash.
I have three drives set up, c:, d:, and e:. C: is the normal drive_c, and d: and e: are subdirectories in my home directory.
Run notepad (wine application). File->save as. Now, drill up the directories, and move out of the wine directories into the host OS filesystem all the way until in the root directory. Go to, say / bin and save the file. Saves, but the file is written to c: (~/.wine/drive_c) instead of /bin.
Run notepad. File->save as. Now drill all the way up until the very top. Two entries: "/" and "my computer". Try to go to "/". Crash. This doesn't happen all the time.
There is nothing special about notepad. The behavior is the same with the windows applications I run under wine.
