QuickTime
CVE-ID: CVE-2010-1818
Available for: Windows 7, Vista, XP SP2 or later
Impact: Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution
Description: An input validation issue exists in the QuickTime ActiveX control. An optional parameter '_Marshaled_pUnk' may be passed to the ActiveX control to specify an arbitrary integer that is later treated as a pointer. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed by ignoring the '_Marshaled_pUnk' parameter. This issue does not affect Mac OS X systems. Credit to HBelite working with TippingPoint's Zero Day Initiative for reporting this issue.

Available for: Windows 7, Vista, XP SP2 or later
Impact: Viewing an image in a maliciously prepared directory may lead to arbitrary code execution
Description: A path searching issue exists in QuickTime Picture Viewer. If an attacker places a maliciously crafted DLL in the same directory as an image file, opening the image file with QuickTime Picture Viewer may lead to arbitrary code execution.
