According to vulnerability research company Secunia, the number of vulnerabilities is expected to double in 2010 compared to last year. Apple leads in number of vulnerabilities, Mozilla has the fewest, while Adobe registered the steepest climb. Secunia's half year report for 2010 (PDF) reveals that the number of vulnerabilities reported in the first six month of this year represents ninety percent of the one registered for the entire 2009. Based on this trend, the Danish vulnerability intelligence vendor estimates that by the end of the year, that number will almost double to reach 760 vulnerabilities. The company data also reveals that since 2005 forward a group of ten vendors comprised of Apple, Oracle, Microsoft, HP, Adobe, IBM, VMware, Cisco, Google and Mozilla, have been responsible for almost 38% of the total number of vulnerabilities reported each time. The order in that enumeration is also the order determined by Secunia based on number of vulnerabilities.
