Bumper security update from Adobe

Warwick Ashford

Adobe's latest quarterly security update covers Flash, Shockwave, Reader, Acrobat, ColdFusion, LifeCycle and Blaze.

After only nine days, another "critical" zero-day exploit has been fixed in Adobe Flash player. Adobe has released updates for Windows, Mac OS X, Solaris and Linux, with updates for the Android version of Flash Player expected before the end of the week.

"Shockwave player for Windows and Mac saw 24 vulnerabilities fixed this quarter, begging the question of why anyone still installs this software," said Chester Wisniewski, senior security advisor at Sophos Canada.

All 24 of the vulnerabilities covered by the update can lead to remote code execution, says Adobe.

That is an extremely large attack surface for something hardly used on modern websites, he wrote in a blog post.

Adobe Reader and Acrobat have also been patched to address critical vulnerabilities. Adobe has fixed 13 vulnerabilities, some of which only apply to Adobe Reader X and were patched in previous emergency releases for other versions.

Most importantly, says Wisniewski, Adobe Acrobat 10.1 now includes the sandbox mode made available earlier this year in Adobe Reader X. The latest releases can be retrieved by choosing "Help", then "Check for updates", or by visiting http://get.adobe.com/reader.

Lifecycle and Blaze have been updated to address two important security vulnerabilities. More information on the flaws and how to patch is available in Adobe security bulletin APSB11-15.

Adobe ColdFusion also has two important security vulnerabilities that could lead to denial of service (DoS) and cross-site request forgery (CSRF) problems. Details are available in Adobe security bulletin APSB11-14.

"I would like to commend Brad Arkin [senior director of product security and privacy at Adobe] and the Adobe team on being much more reliable on releasing their updates in a predictable manner. The information provided by Adobe makes it easier for researchers and IT administrators alike to maintain their software," wrote Wisniewski.

According to Wisniewski, there is still work to do on reducing the number of out-of-band updates and the quantity of flaws, but Adobe is heading in the right direction.
