This is a table of software versions indexed by the name of the software and a set of version ranges that are declared to be vulnerable for that software.

Types

Software::VulnerableVersionRange

Type:

record

min: Software::Version &optional

The minimal version of a vulnerable version range. This field can be undefined if all previous versions of a piece of software are vulnerable.

max: Software::Version

The maximum vulnerable version. This field is deliberately not optional because a maximum vulnerable version must always be defined. This assumption may become incorrect if all future versions of some software are to be considered vulnerable. :)
