Mediawiki 1.18.0 Information Disclosure

`CVE-2014-1686 -- Information disclosure: webserver source path in  
Mediawiki 1.18.0  
  
When a user create a new file (eg: image) with a name containing *, it  
leads to webserver file path disclosure, after having uploaded the file,  
when thumbail creation occurs.  
  
I did not succeed in obtained remote shell code execution, but this may  
be a vulnerable path.  
  
  
Counter-measure: refuse creation of file containing a *  
backported the patch in 1.19 and 1.20  
Note, permissions when creating thumbnails can have the same outcome.
