R Ginski, If there was some sort of buffer overflow/other way of causing the code to function in a manner inconsistant with it's design due to the content/formatting of the .jpg image then yes, there could be a payload designed to be set off upon viewing of the .jpg image. Otherwise, the .jpg image specifies (simplified) values of pixels in a compressed format and thus the .jpg specification does not include the ability to run code by default. -Jove On 7 Nov 2001 rginski () co pinellas fl us wrote:
Mailer: SecurityFocus Is it possible for a virus to infect a jpeg (*.jpg) file, then the jpg file to infect other files?...without changing the files characteristics? In other words, a jpeg file (file.jpg) is infected and it remains "infected_file.jpg". It is possible for a file type as jpeg to have a payload or cause damage although it's just being viewed? Perhaps something like steganagraphy...except embedding vbs (or something) causing infection by way of the viewer? I guess another way of asking the question is: Is it possible to get infected by just viewing jpeg files? I realize that's a "wide open question" I just don't know how else to explain myself. Thanks in advance for your patience and help.
