TITLE:
Microsoft Windows HTML Help File Processing Vulnerability

SECUNIA ADVISORY ID:
SA38916

VERIFY ADVISORY:
http://secunia.com/advisories/38916/

DESCRIPTION:
edu has discovered a vulnerability in Microsoft Windows, which can be
exploited by malicious people to potentially compromise a user's
system.

The hhctrl.ocx "HtmlHelpA()" function opens CHM files placed in the
current directory if a relative path is received as an argument. This
can be exploited to execute arbitrary JavaScript code in a local
security context by e.g. tricking a user into opening a ".txt" file
placed in the same directory with a specially crafted notepad.chm
file, opened by notepad.exe when the F1 key is pressed inside the
document.

Successful exploitation allows execution of arbitrary commands, but
additionally requires that the user is tricked into clicking a topic
in the malicious help file.

The vulnerability is confirmed on a fully patched Windows XP SP3, and
also reported in Windows 2000 SP4.

SOLUTION:
Avoid pressing F1 inside documents or images placed in untrusted
directories.
