Adobe Flash Warning Arrives As It Patches Shockwave

A new vulnerability in Adobe Flash Player was reported just as it issued a patch for Shockwave

Call it a “good news, bad news” situation for Adobe Systems. On the one hand, the company patched a number of vulnerabilities today in Shockwave Player; on the other, it issued a new advisory on a zero-day bug in Adobe Flash Player.

The Flash Player vulnerability (CVE-2010-3654) affects versions and earlier versions on Windows, Macintosh, Linux and Solaris operating systems, as well as Flash Player and earlier versions for Android. It also impacts the authplay.dll component that ships with Adobe Reader 9.4 and earlier 9.x versions for Windows, Macintosh and Unix systems, as well as Adobe Acrobat 9.4 and earlier 9.x versions for Windows and Macintosh.

Adobe Promises A Fix Is Being Finalised

“This vulnerability could cause a crash and potentially allow an attacker to take control of the affected system,” Adobe warned. “There are reports that this vulnerability is being actively exploited in the wild against Adobe Reader and Acrobat 9.x. Adobe is not currently aware of attacks targeting Adobe Flash Player.”

“We are in the process of finalising a fix for the issue and expect to provide an update for Flash Player 10.x for Windows, Macintosh, Linux, and Android by November 9, 2010,” the company said. “We expect to make available an update for Adobe Reader and Acrobat 9.4 and earlier 9.x versions during the week of November 15.”

While users wait for the patch for the Flash Player vulnerability, users can delete, rename or remove access to the authplay.dll file that ships with Adobe Reader and Acrobat, Adobe advised. Doing so however will cause a non-exploitable crash or error message when opening a PDF file that contains Flash content. Instructions for doing this can be found in the advisory.

At the same time the company issued the advisory, it shipped a fix for a zero-day bug in Shockwave Player into a massive update that plugged 10 other vulnerabilities as well. On October 21, Adobe warned about a memory corruption vulnerability (CVE-2010-3653) in Shockwave Player versions, and earlier, on Windows and Mac had been discovered. Six days later, the company warned the issue was under attack.
