It turns out that `Component#version` differs from the PURL's version, in that it contains the epoch (e.g. `1:`). Trivy does not expect the epoch as part of the version field, since it has its own dedicated field.

For example:

```json
{
  "type": "library",
  "name": "dbus-common",
  "version": "1:1.12.20-8.el9",
  "purl": "pkg:rpm/redhat/[email protected]?arch=noarch&distro=redhat-9.4&epoch=1"
},
```
