Adobe plugs critical Flash Player hole

More than 30 others patched too

Seven Steps to Software Security

Adobe Systems on Thursday made good on a promise to rid its ubiquitous Flash media player of a critical vulnerability that criminals are exploiting to install malware on end user machines.

The security update is available for versions 10.0.45.2 and earlier of Flash for Windows, Mac OS X, and Linux. Last week, Adobe warned that the vulnerability allows attackers to take complete control of vulnerable machines when they view websites that contained specially manipulated Flash content. A related vulnerability that's also being actively exploited in Adobe's Reader and Acrobat applications won't be available until June 29, the company said.

According to Websense and other security firms, the security bugs are being targeted in emails that prompt recipients to open booby-trapped websites and PDF documents. The malicious files used in the exploits weren't detected by a single one of the major anti-virus providers as of Wednesday, more than five days after Adobe first disclosed the attacks, Websense said.

Once the exploits are executed, end-user machines are infected with backdoor trojans and other malware, much of which also was not detected by anti-virus software.

With almost three weeks to go before a fix is issued for the Reader and Acrobat bugs, users should take steps to guard against attacks. The best safeguard is to shun the applications altogether and use an alternative one such as Foxit for Windows or Preview for the Mac. If that's not possible, the authplay.dll, AuthPlayLib.bundle or libauthplay.so.0.0.0 files should be deleted on Windows, Mac and Linux machines respectively.

Adobe has more detailed work-around instructions here. The US Computer Emergency Readiness Team has also said that disabling javascript in Reader and Acrobat will also prevent the attacks.

In all, Flash 10.1.53.64, which is available for download here, fixes more than 30 other security flaws. Not that Adobe is out of the woods yet. Shortly after it was released, security researcher Charlie Miller tweeted: "Yippee! My fav flash bug survived another adobe killing field." ®
