Background: Windows Explorer for Windows XP will automatically parse .WMF files for validity when browsing the directory that contains them. No need to click on anything at all. Bug: GDI32!SetMetaFileBitsEx (which does the parsing) does not check for records of zero length, resulting in an infinite loop when one is encountered, and making the system very slow. Demo: can be done in 24 bytes. Very silly. -- _______________________________________________ Full-Disclosure - We believe in it. Charter: http://lists.netsys.com/full-disclosure-charter.html
