-/* why this routine ?
- Problem: link attack
- Bad user wants to overwrite a file (mywork.txt) of good user.
- File permissions of mywork.txt is 700 so that bad user can not
- change or overwrite the file. Directory permissions allow bad user
- to write into directory. Bad user sets symlink from a file that good
- user will write soon (image.pnm) to mywork.txt.
- ==> Good user overwrites his own file, he is allowed to do so.
-
- Solution: remove file.
- Create outputfile and make sure that it does not exist while creation.
-
- The file is created with the requested image-file permissions.
-
- Note: This case is a bit curious because it is only a small part of a larger problem:
- When other users have write access to the directory they simply can move
- mywork.txt to image.pnm. If they do it in the right moment the file is
- overwritten without any notice of good user. If they do it long before xsane
- wants to write image.pnm then xsane will possibly ask if image.pnm shall be
- overwritten. So the real solution is to make the direcoty permissions safe!!!
- But some users asked for this and so I added this.
-
-
- This routine shall not be called for temporary files because temp files shall not
- be removed after they have been created safe. (Although a temporary file should
- not be a symlink so there should be no problem with this)
