PC World posted a workaround for a zero-day security flaw in Windows XP

Earlier this week was Microsoft's Patch Tuesday for June--a busy Patch Tuesday with ten new security bulletins fixing 34 different vulnerabilities. However, there is now a publicly disclosed vulnerability with potentially dire consequences that didn't make the list of patches this month. IT administrators need to understand the risks, and act now to mitigate the threat and protect Windows XP systems from the HCP protocol vulnerability.
