Description Eugene Teo (Security Response) 2008-09-29 03:36:07 EDT
Description of problem:
Originally from Mark Fasheh <mark.fasheh@oracle.com>

generic_file_splice_write() does not remove S_ISUID or S_ISGID. This is inconsistent with the way we generally write to files.

Proposed upstream patch:
Comment 2 Eugene Teo (Security Response) 2008-09-29 04:03:11 EDT
This requires should_remove_suid(), and __remove_suid() from bug #463661.
Comment 5 Eugene Teo (Security Response) 2008-10-02 20:53:43 EDT
This bug has similar consequences as CVE-2008-4210.
