Adobe rolls out emergency update for Flash Player

PanARMENIAN.Net - Adobe has urged users of its Flash Player plug-in to install an update to protect themselves against the risk of hackers hijacking their PCs. It cited a "critical vulnerability" in older versions and said it had become aware of reports that cybercriminals had worked out a way to exploit it, according to BBC News.

A new version of the multimedia player has been made available for download for Windows, Mac and Linux computers. This is the latest in a series of setbacks for the company.

The California-based software maker acknowledged that usernames and encrypted passwords had been stolen from about 38 million of its active account holders last year. And Flash vulnerability alerts frequently appear on security firms' warning lists.

"Adobe does seem to have an unfortunate history of people finding security flaws with Flash that require updates," independent security consultant Alan Woodward told the BBC. "What Adobe seem to have done in this case is put out a warning, but it has not given as much information as other firms would normally do when issuing such a security advisory. That might be them trying to avoid giving the hackers too much information whilst still telling people there is a problem."

Adobe only describes the flaw as being an "integer underflow vulnerability" in its report.

The company thanks two researchers at the Kaspersky Lab for alerting it to the problem. The Russian security company has not commented on the topic yet, but might reveal more information at a conference it is hosting in the Dominican Republic this weekend.

In the meantime, the BBC says, Apple is blocking the use of older versions of Flash on its Safari web browser.

The firm introduced a "sandbox" feature to its Mavericks operating system in October that stops the Flash plug-in from running automatically. Users must first give it permission to activate and Apple can also disable the software remotely.

Adobe had previously worked with Google, Microsoft and Mozilla to offer similar protective measures. Adobe notes that users of Chrome, Internet Explorer 10 and Internet Explorer 11 should all see their browsers automatically update themselves to include the latest version of Flash.

Although many websites still use Flash to provide videos, graphics, games and other content, large numbers of developers have switched to using the web language HTML 5 to create such effects.

This has been spurred on by the fact that Flash is not supported on Apple's iOS platform and has been pulled from Google's Android Play store.

Adobe itself acknowledged in 2011 that HTML 5 offered the "best solution" for mobile devices because it was universally supported.

However, it continues to develop the software for PCs, suggesting it can deliver smoother animations and higher-quality 3D video games graphics than alternative technologies.
