March 25, ZDNet – (International) Study: More than 50% of Global 500 use vulnerable open source components. According to a joint research report issued March 25 by Sonatype and Aspect Security, more than 50% of the world's largest corporations have open source applications with security vulnerabilities. That is because more than 80% of software applications built in-house by enterprise developers incorporate open source components and frameworks that may be vulnerable. The report — based on a survey of 2,550 developers, architects and analysts — maintains that the widely held view that open source software consistently "overlooks ecosystem flaws," chiefly the lack of a notification system alerting developers about vulnerabilities and new versions with fixes.
