Today’s batch: fixes for two “critical” vulnerabilities and one “moderate” vulnerability.
Windows XP users need the moderate patch and one of the critical patches. Windows Exchange users need the other critical patch.
Fine print: The critical patch for XP users (and Windows 98 and ME users as well) fixes a vulnerability in Adobe’s Macromedia Flash Player that could allow remote code execution. The moderate patch for XP users (and Windows 2000 and Server 2003 users) fixes a vulnerability in the Microsoft Distributed Transaction Coordinator that could allow a denial of service attack. The critical patch for Exchange is for a vulnerability that could allow remote code execution.
