Multiple vulnerabilities were identified in Microsoft Windows, which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service.
The first issue is due to heap overflow errors in "GDI32.DLL" when processing malformed Windows Metafile (WMF) and Enhanced Metafile (EMF) images, which could be exploited by remote attackers to compromise a vulnerable system by convincing a user to visit a malicious Web site (using Internet Explorer), read a malicious email (using Outlook), or open a specially crafted Office document containing a malicious image.
The second flaw is due to an integer overflow error in the "PlayMetaFileRecord()" function of "GDI32.DLL" that does not properly handle malformed Windows Metafile (WMF) images, which could be exploited by remote attackers to compromise a vulnerable system by convincing a user to visit a malicious Web site (using Internet Explorer), read a malicious email (using Outlook), or open a specially crafted Office document containing a malicious image.
The third vulnerability is due to an error in the "GetEnhMetaFilePaletteEntries()" function of "GDI32.DLL" when processing malformed Enhanced Metafile (EMF) images, which could be exploited by remote attackers to cause a denial of service via a malicious image.
