Apple QuickTime 7.6.7 “_Marshaled_pUnk” Code Execution Vulnerability and Metasploit Exploit

A new (read: yet another) 0day QuickTime vulnerability has been discovered by researcher Ruben Santamarta which leads to arbitrary client-side code execution. The vulnerability, which affects QuickTime <= 7.6.7 on Windows XP, Vista and 7 and defeats DEP and ASLR, is due to a flaw in the way the QuickTime ActiveX controller handles a supplied parameter and treats it as a trusted pointer.

This vulnerability can be exploited by luring the victim to a malicious web page. A heap-spraying Metasploit module has already been published which exploits this issue.

Read Reuben’s original advisory and then get Firefox.
