- Adobe (Macromedia) Flash Player 6
Microsoft has released updates to address a vulnerability in the Windows Embedded Open Type (EOT) font engine. Microsoft has also published an Advisory about multiple vulnerabilities in Adobe (Macromedia) Flash Player 6 that is included with Windows XP.
Microsoft Security Bulletin MS10-001 describes a vulnerability in the Embedded Open Type (EOT) font engine in Windows. Microsoft Security Advisory (979267) recommends that Windows XP users remove or upgrade Adobe Flash Player 6 (formerly Macromedia Flash Player) that is included with Windows XP. Vulnerability Note VU#204889 discusses one vulnerability in Flash Player 6 and provides several workarounds.
These vulnerabilities could be exploited by loading specially crafted fonts or Flash content via Internet Explorer.
Microsoft assigns the EOT font vulnerability a "low" severity rating in most current versions of Windows and notes that reliable code execution is unlikely. The severity rating for Windows 2000, however, is "critical."
A remote, unauthenticated attacker could execute arbitrary code, gain elevated privileges, or cause a vulnerable application to crash.
