Adobe has released a critical patch to cover a pair of serious vulnerabilities affecting the Adobe Flash Media Server (FMS) 3.5.2 and earlier versions. The update is available for all platforms and addresses issues that allow an attacker to run malicious code on the affected system. It addresses a resource exhaustion vulnerability that could could lead to a Denial of Service (DoS) (CVE-2009-3791), and a directory traversal vulnerability. The fix is available to all platforms, but Adobe recommends FMS users install FMS version.
