Microsoft Windows EOT Font and Adobe Flash Player 6 Vulnerabilities
Original release date:
Last revised: --
Source: US-CERT
Systems Affected
* Microsoft Windows and Internet Explorer
* Adobe (Macromedia) Flash Player 6
Overview
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.
I. Description
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."
II. Impact
A remote, unauthenticated attacker could execute arbitrary code,
gain elevated privileges, or cause a vulnerable application to
crash.
III. Solution
Apply updates from Microsoft
Microsoft Security Bulletin MS10-001 provides updates for the EOT
font vulnerability. The security bulletin describes any known
issues related to the updates. Administrators are encouraged to
note these issues and test for any potentially adverse effects.
Administrators should consider using an automated update
distribution system such as Windows Server Update Services (WSUS).
Upgrade, Remove, or Disable Adobe Flash Player 6
Adobe Flash Player 6 is included with Windows XP. Adobe has
addresssed these vulnerabilities in newer versions of Flash Player.
Upgrade to a more recent version of Flash Player (such as Flash
Player 10). Alternatively, uninstall Flash Player or set the kill
bit for the Flash Player ActiveX control as described in Microsoft
Security Advisory (979267) and Vulnerability Note VU#204889.
