Open source bugs have soared in the past year

source have skyrocketed in the last , according to a report from open source licence management and security software vendor WhiteSource.

The number of open source sat steady at just over 4,000 in 2017 and 2018, the report said, having more than doubled the number of bugs from pre-2017 figures that had never before broken the 2,000 mark.

Then, 2019’s numbers soared again, topping 6,000 for the first time, said WhiteSource, representing a rise of almost 50%.

By far the most common weakness enumeration (CWE – a broad classifier of different bug types) in the open source world is cross-site scripting (XSS). This kind of flaw accounted for almost one in four bugs and was the top for all languages except C. This was followed by improper input validation, buffer errors, out-of-bound reads, and information exposure. Use after free, another memory flaw, came in last with well under 5% of errors.

WhiteSource had some harsh words for the national vulnerability database (NVD), which it said only contains 84% of the open source vulnerabilities that exist. It adds that many of these vulnerabilities are reported in other places first and only make it into the NVD much later.
