Microsoft, Netscape battle over browser hole
Microsoft Corp. and Netscape Communications Corp. are at odds over who is to blame for a browserrelated security hole that could make Web sites vulnerable to attack from hackers.
Microsoft Corp. and Netscape Communications Corp. are at odds over who is
to blame for a browser-related security hole that could make Web sites vulnerable
to attack from hackers.
Netscape's Communicator browser includes JavaScript, a scripting language
that enables Web authors to create interactive Web sites. It is supported
by script from Microsoft's rival browser, Internet Explorer (IE). However,
some IE scripts that are meant to be accessed only by the user are exposed
to attack in the Communicator browser, a Microsoft official and an independent
analyst confirmed Friday.
Microsoft said it is up to Netscape to protect the privacy of the scripts
in Communicator, no matter where they originated.
"The Microsoft Internet Explorer security model allows a Web site to
run any script or program that it trusts," said Scott Culp, a Microsoft
security program manager. "The program exposes some fairly powerful functionality
that allows a hostile Web site to glean information from a user's machine."
Netscape places the blame for the security hole firmly at Microsoft's
door. "It's only the installation and use of Internet Explorer that leave
the user vulnerable," said Eric Krock, a Netscape group manager for tools
and components.
One security analyst agreed and said Microsoft should fix the bug itself.
"Microsoft built the architecture that made [the hole] possible," said David
Perry, a spokesman for antivirus software vendor Trend Micro Inc.
However, Microsoft said it is Netscape's responsibility to protect the
script from attack. "The real problem is Netscape Communicator taking a
powerful script and putting it out on your computer in a locale where any
Web site can find it out and run it," Culp said.
No incidents of a breach of the hole have been reported.
