Macromedia Inc. warned yesterday of a "critical" security flaw in the
latest version of its Flash animation player and advised users to
install a new version that it released on the Web to fix the problem.  
The security flaw affects Version 6 of the Macromedia Flash Player,
which was released a year ago this month and has been installed on an
estimated 75% of PCs worldwide, according to the company.

The vulnerability affects the integrity of the player's "sandbox,"  
which is supposed to act as a cordoned-off area where Flash code
retrieved from the Web can be run safely, without access to a user's
files. The flaw could allow a malicious hacker to run native code on a
user's computer, outside the sandbox, possibly without the user's
knowledge, according to information on the company's Web site.

No users had reported having been affected by the problem as of
yesterday evening, a Macromedia representative said. Nevertheless, the
San Francisco-based company advised users to download a new version of
the player -- Version 6.0.79.0 -- from its Web site immediately.

Besides fixing the latest vulnerability, the new version serves as a
cumulative patch, fixing other security flaws reported since the
product's release, including memory buffer overflows, Macromedia said.  
It also offers other tweaks intended to boost performance of the
product.

The company offered few other details, saying only that the
vulnerability was reported to Macromedia "recently" by a third party.

The bulletin, with a link to the download site, is at
www.macromedia.com/v1/handlers/index.cfm?ID=23821.

Macromedia sought to assure users of the steps it takes to make its
products secure. These include hiring experts outside the company to
run "penetration" tests on its products before they are released, it
said. The company recently appointed Paul Madar as chief security
officer to oversee security in its products.

The company has issued more than 15 security patches, bulletins and
notifications over the past year, according to its Web site. It
recently implemented a ranking system similar to that used by
Microsoft Corp. and other software vendors, designating
vulnerabilities as "critical," "important," "moderate" and "low."

"The testing program finds many issues prior to product shipment. But
while we strive to improve the program, we can still miss issues,"  
Madar wrote in a recent posting on the company's Web site.

Flash is the most popular format for creating animation for Web sites.  
In December, the free Flash Player had been installed on 98% of PCs
worldwide, or close to half a billion machines, and about
three-quarters of them were running Flash Player 6, according to a
survey conducted for Macromedia by research company NPD Online.
