Overview
Microsoft has released updates that address critical vulnerabilities
in Windows, Outlook, and Exchange. Exploitation of these
vulnerabilities could allow a remote, unauthenticated attacker to
execute arbitrary code or cause a denial of service on a vulnerable
system.
I. Description
Microsoft Security Bulletins for January 2006 address vulnerabilities in Microsoft
Windows, Outlook, and Exchange. Further information is available in
the following US-CERT Vulnerability Notes:
VU#915930 -
Microsoft embedded web font buffer overflow
A heap-based buffer overflow in the way Microsoft Windows processes embedded web fonts may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
(CVE-2006-0010)
VU#252146 -
Microsoft Outlook and Microsoft Exchange TNEF decoding vulnerability
Microsoft Outlook and Microsoft Exchange contain an unspecified vulnerability in processing TNEF attachments. This may allow a remote, unauthenticated attacker to execute arbitrary code on a system running the vulnerable software.
(CVE-2006-0002)
II. Impact
Exploitation of these vulnerabilities may allow a remote,
unauthenticated attacker to execute arbitrary code with the
privileges of the user. If the user is logged on with administrative
privileges, the attacker could take complete control of an affected
system. An attacker may also be able to cause a denial of service.
III. Solution
Apply Updates
Microsoft has provided the updates for these vulnerabilities in the
Security Bulletins and on the Microsoft Update site.
