A remote code execution vulnerability exists in Microsoft Internet Explorer. The vulnerability exists as an invalid pointer reference within Internet Explorer. It is possible under certain conditions for the invalid pointer to be accessed after an object is deleted. In a specially-crafted attack, in attempting to access a freed object, Internet Explorer can be caused to allow remote code execution.

It is believed that while Internet Explorer 5.01 Service Pack 4 on Microsoft Windows 2000 Service Pack 4 is not affected, Internet Explorer 6 Service Pack 1 on Microsoft Windows 2000 Service Pack 4, and Internet Explorer 6, Internet Explorer 7 and Internet Explorer 8 on supported editions of Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 are affected.

It is possible under certain conditions for the invalid pointer to be accessed after an object is deleted. In a specially-crafted attack, in attempting to access a freed object, Internet Explorer can be caused to allow remote code execution.

Microsoft addresses the following vulnerability in its January batch of patches:

• (MS10-001) Vulnerability in the Embedded OpenType Font Engine Could Allow Remote Code Execution (972270)
  This security update resolves a privately reported vulnerability in Microsoft Windows.

Use-after-free vulnerability in the Doc.media.newPlayer method in Multimedia.api in Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, allows remote attackers to execute arbitrary code via a crafted PDF file using ZLib compressed streams, as exploited in the wild in December 2009.

Trend Micro advises users about an existing vulnerability in Adobe Illustrator. The exploit happens when the said application fails to successfully parse comments from EPS (Encapsulated PostScript) files, leading to a buffer overflow.

Once the vulnerability is successfully exploited, attackers can be allowed to execute arbitrary code on the compromised system, allowing them to gain complete control of it.
