Mudit,
Can you explain exactly what Bloodhound.PDF.21 thinks is the problem. I've read the tech description you linked in your response but it doesn't really explain anything. It appears to be complaining about a possible vulerability. Is that right?
To answer your question AravindKM, nothing in this area of the system has been changed in some time. The action of loading the pdf with data is using an Adobe library so I can't see the code being called and that library hasn't changed in years.
It looks to be quarintining temp or cached files. In one example, it complained about fdfaction.fdf and a temp file called arg87.tmp. This is being found during a "realtime protection scan". Part of the problem is that I can't reproduce it at my site. I'm getting various reports from user sites.
Thanks,
Rick
