Apple QuickTime '_Marshaled_pUnk' Remote Code Execution Vulnerability

Risk

High

Date Discovered

August 30, 2010

Description

Apple QuickTime is prone to a remote code-execution vulnerability that affects the 'QTPlugin.ocx' ActiveX control because it fails to sufficiently validate user-supplied data. An attacker can exploit this issue by enticing an unsuspecting user to view a malicious webpage. Successful exploits will allow the attacker to execute arbitrary code within the context of the application, typically Internet Explorer, that uses the ActiveX control. Windows 7, Vista, and XP platforms are vulnerable; other platforms may also be affected.

Recommendations

Run all software as a nonprivileged user with minimal access rights.

To limit the potential damage that a successful exploit may achieve, run all nonadministrative software as a regular user with the least amount of privileges required to successfully operate.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not accept or execute files from untrusted or unknown sources.

To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.

Do not follow links provided by unknown or untrusted sources.

Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.

Since these issues may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
Vendor updates are available. Please see the references for more information.
