In any given year, myriad vulnerabilities are found in software products from multiple vendors across the IT landscape.
In 2015 there were a total of 16,081 vulnerabilities in 2,484 products from 263 vendors, according to the Vulnerability Review 2016 report from Secunia Research at Flexera Software.

The 2016 report looked at fewer product and vendors than the 2015 report (reflecting the year 2014), when 3,907 products from 514 vendors were evaluated.

The decline in the number of vendors and products examined is a methodology issue as Secunia Research refocused the study to monitor only the systems and applications in use in the environments of customers of Flexera Software’s Software Vulnerability Management product line, according to the researchers.

Despite the reduction in the number of vendors in the study, there were still 25 products that had zero-day vulnerabilities.

According to the study, the number of vulnerabilities saw a 77 percent increase over five years and a 47 percent increase in the past year alone. eWEEK examines key takeaways from the report.
