The flaws affect the current versions of Adobe Flash Player 9 and 10 for Windows, Macintosh and Linux operating systems and Adobe AIR 1.5.1 and earlier versions, Adobe said in its security bulletin.
The update addresses 10 vulnerabilities in total. Specifically, it addresses a bug caused by a flaw in Microsoft's Active Template Library (ATL) that Microsoft patched in Internet Explorer and Visual Studio on Tuesday. This vulnerability could allow an attacker to take control of an affected system, Adobe said.
In addition, the update addresses a memory corruption vulnerability that Adobe said last week was being exploited in the wild in targeted attacks. The critical bug, which affects not only Flash Player and AIR, but also Adobe Reader and Acrobat, could cause a computer to crash or enable an attacker to take control of an affected system. Adobe said it plans to update Adobe Reader and Acrobat to address this vulnerability on Friday.
Also, Thursday's update addresses a clickjacking vulnerability, which could allow an attacker to trick users into clicking a link or dialogue that they did not intend to. A number of other issues that could lead to code execution and one that could lead to information disclosure also were mitigated with this update, Adobe said.
