Overview
Microsoft has released updates that address critical vulnerabilities in Windows and Internet Explorer. Exploitation of these vulnerabilities could allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial of service.
I. Description
Microsoft Security Bulletins for June, 2005 address a number of vulnerabilities in Windows, Internet Explorer, Outlook Express, Outlook Web Access, ISA Server, the Step-by-Step Interactive Training engine, and telnet. Further information about the more serious vulnerabilities is available in the following Vulnerability Notes:
VU#189754 - Microsoft Internet Explorer buffer overflow in PNG image rendering component
A buffer overflow in the PNG image rendering component of Microsoft Internet Explorer may allow a remote attacker to execute code on a vulnerable system.
(CAN-2005-1211)
VU#489397 - Microsoft Server Message Block vulnerable to buffer overflow
Microsoft Server Message Block (SMB) is vulnerable to a buffer handling flaw when processing incoming SMB packets that may lead to remote code execution.
(CAN-2005-1206)
VU#851869 - Microsoft HTML Help input validation error
Microsoft HTML Help fails to properly validate input data, allowing a remote attacker to execute arbitrary code.
(CAN-2005-1208)
II. Impact
Exploitation of the most serious of these vulnerabilities could allow a remote, unauthenticated attacker to execute arbitrary code with SYSTEM privileges. This would allow an attacker to take complete control of a vulnerable system. An attacker could also execute arbitrary code with user privileges, or cause a denial of service.
III. Solution
Apply updates
Microsoft has provided the patches for these vulnerabilities in the
Security Bulletins and on Windows Update.
Workarounds
Please see the individual vulnerability notes for workarounds.
