Description xademax 2014-03-20 14:57:15 UTC 
I noticed some invalid read while parsing raw data (an SWF in this example) in HTML mode.

I'm using libxml2-2.9.1.
There is everything in the attachment to reproduce the bug :
- C code based on parse3.c example
- SWF file that caused the bug
- A valgrind log for help

I suspect a bug in htmlParseNameComplex() (HTMLparser.c:2488)
I tried to replace line 2514 "NEXTL(l);" by "NEXTL(len);l=0;" and the invalid are gone but not sure at all of what i did ...

I hope this helps ...
