RealNetworks Realplayer QCP Parsing Heap Overflow

Description

This module exploits a heap overflow in Realplayer when handling a .QCP file. The specific flaw exists within qcpfformat.dll. A static 256 byte buffer is allocated on the heap and user-supplied data from the file is copied within a memory copy loop. This allows a remote attacker to execute arbitrary code running in the context of the web browser via a .QCP file with a specially crafted "fmt" chunk. At this moment this module exploits the flaw on Windows XP IE6, IE7.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
