Flaw could allow malicious code to be run.

Adobe has issued a security update after a vulnerability was revealed in its Shockwave player.

Following detection by Secunia, Adobe confirmed that critical vulnerabilities have been identified in Adobe Shockwave Player and earlier versions, on the Windows and Macintosh operating systems.

Adobe said: “The vulnerabilities could allow an attacker, who successfully exploits the vulnerabilities, to run malicious code on the affected system. Adobe has provided a solution for the reported vulnerabilities. It is recommended that users update their installations to the latest version.”

The Common Vulnerabilities and Exposures (CVE) project assigned the code CVE-2009-4003 for the vulnerability. Secunia said that the vulnerability can be "exploited by malicious people to potentially compromise a user's system".

It is caused due to an integer overflow error when processing a certain Shockwave 3D block. This can be exploited to corrupt memory via a specially crafted Shockwave file. Successful exploitation may allow execution of arbitrary code.

US-CERT encouraged users and administrators to review Adobe Security Bulletin APSB10-03 and apply any necessary updates to help mitigate the risks.
