Microsoft DirectX QuickTime Movie Parser Filter NULL Byte Overwrite RCE
CVE-2009-1537 is a remote code execution vulnerability in the QuickTime Movie Parser Filter within quartz.dll, part of DirectShow in Microsoft DirectX 7.0 through 9.0c. The flaw is described as a NULL byte overwrite triggered while parsing a crafted QuickTime media file. A remote attacker can deliver a malicious .mov or other QuickTime-formatted media file and, if it is opened by a user on a vulnerable system, memory corruption occurs in the DirectShow parsing path, potentially allowing arbitrary code execution. Affected platforms cited in the provided content include Windows 2000 SP4, Windows XP SP2/SP3, and Windows Server 2003 SP2. The issue was publicly reported and exploited in the wild in 2009, and is also referred to as the "DirectX NULL Byte Overwrite Vulnerability."
