Default Flaws Are Detected in Microsoft’s Vista

Flaws Are Detected in Microsoft’s Vista
By JOHN MARKOFF

SAN FRANCISCO, Dec. 24 — Microsoft is facing an early crisis of
confidence in the quality of its Windows Vista operating system as
computer security researchers and hackers have begun to find potentially
serious flaws in the system that was released to corporate customers
late last month.

On Dec. 15, a Russian programmer posted a description of a flaw that
makes it possible to increase a user’s privileges on all of the
company’s recent operating systems, including Vista. And over the
weekend a Silicon Valley computer security firm said it had notified
Microsoft that it had also found that flaw, as well as five other
vulnerabilities, including one serious error in the software code
underlying the company’s new Internet Explorer 7 browser.

The browser flaw is particularly troubling because it potentially means
that Web users could become infected with malicious software simply by
visiting a booby-trapped site. That would make it possible for an
attacker to inject rogue software into the Vista-based computer,
according to executives at Determina, a company based in Redwood City,
Calif., that sells software intended to protect against operating system
and other vulnerabilities.

Determina is part of a small industry of companies that routinely pore
over the technical details of software applications and operating
systems looking for flaws. When flaws in Microsoft products are found
they are reported to the software maker, which then produces fixes
called patches. Microsoft has built technology into its recent operating
systems that makes it possible for the company to fix its software
automatically via the Internet.

Despite Microsoft assertions about the improved reliability of Vista,
many in the industry are taking a wait-and-see approach. Microsoft’s
previous operating system, Windows XP, required two “service packs”
issued over a number of years to substantially improve security, and new
flaws are still routinely discovered by outside researchers.

On Friday, a Microsoft executive posted a comment on a company security
information Web site stating the company was “closely monitoring” the
vulnerability described by the Russian Web site. It permits the
privileges of a standard user account in Vista and other versions of
Windows to be increased, permitting control of all of the operations of
the computer. In Unix and modern Windows systems, users are restricted
in the functions they can perform, and complete power is restricted to
certain administrative accounts.

“Currently we have not observed any public exploitation or attack
activity regarding this issue,” wrote Mike Reavey, operations manager of
the Microsoft Security Response Center. “While I know this is a
vulnerability that impacts Windows Vista, I still have every confidence
that Windows Vista is our most secure platform to date.”

On Saturday, Nicole Miller, a Microsoft spokeswoman, said the company
was also investigating the reported browser flaw and that it was not
aware of any attacks attempting to use the vulnerability.

Microsoft has spent millions branding the Vista operating system as the
most secure product it has produced, and it is counting on Vista to help
turn the tide against a wave of software attacks now plaguing
Windows-based computers.

Vista is critical to Microsoft’s reputation. Despite an almost
four-and-half-year campaign on the part of the company, and the best
efforts of the computer security industry, the threat from harmful
computer software continues to grow. Criminal attacks now range from
programs that steal information from home and corporate PCs to growing
armies of slave computers that are wreaking havoc on the commercial
Internet.

Although Vista, which will be available on consumer PCs early next year,
has been extensively tested, it is only now being exposed to the
challenges of the open Internet.

“I don’t think people should become complacent,” said Nand Mulchandani,
a vice president at Determina. “When vendors say a program has been
completely rewritten, it doesn’t mean that it’s more secure from the
get-go. My expectation is we will see a whole rash of Vista bugs show up
in six months or a year.”

The Determina executives said that by itself, the browser flaw that was
reported to Microsoft could permit damage like the theft of password
information and the attack of other computers.

However, one of the principal security advances of Internet Explorer 7
is a software “sandbox” that is intended to limit damage even if a
malicious program is able to subvert the operation of the browser. That
should limit the ability of any attacker to reach other parts of the
Vista operating system, or to overwrite files.

However, when coupled with the ability of the first flaw that permits
the change in account privileges, it might then be possible to
circumvent the sandbox controls, said Alexander Sotirov, a Determina
security researcher. In that case it would make it possible to alter
files and potentially permanently infect a target computer. This kind of
attack has yet to be proved, he acknowledged.

The Determina researchers said they had notified Microsoft of four other
flaws they had discovered, including a bug that would make it possible
for an attacker to repeatedly disable a Microsoft Exchange mail server
simply by sending the program an infected e-mail message.

Last week, the chief technology officer of Trend Micro, a computer
security firm in Tokyo, told several computer news Web sites that he had
discovered an offer on an underground computer discussion forum to sell
information about a security flaw in Windows Vista for $50,000. Over the
weekend a spokesman for Trend Micro said that the company had not
obtained the information, and as a result could not confirm the
authenticity of the offer.

Many computer security companies say that there is a lively underground
market for information that would permit attackers to break in to
systems via the Internet.
