Weston Steimel 15e45a8ce1 add additional vendors for springframework (#945)
The Official CPE dictionary currently contains entries for springframework with three different vendors: springsource, vmware, and pivotal_software.  This appears to be because ownership has changed over time.

Sambhav Kothari 2a7325a965 Fix CPE encode/decode when it contains special chars (#714)
* Fix CPE generation when the generated CPE contains invalid characters

Currently syft seems to generate invalid CPEs which do not
conform with the official CPE spec. This is because the underlying
nvdtools library is not a completely spec compliant implementation
and has some interesting bugs/issues.

The following are the list of issues I have encountered with nvdtools:

1. It parses strings which are not CPEs incorrectly as valid CPEs. This
messes up our filter function which is supposed to filter out any
incorrect CPEs we generate. In order to fix this, I have introduced
a new regex in the NewCPE function which follows the upstream spec and
filters out any incorrect CPEs.

2. Introduce wfn.WFNize for any cpe attributes we infer from packages.
This ensures that we are escaping and quoting any special characters
before putting them into CPEs. Note that nvdtools has yet another bug
in the WFNize function, specifically the "addSlashesAt" part of the
function which stops the loop as soon as it encounters ":" a valid
character for a WFN attribute after quoting, but the way nvdtools
handles it causes it to truncate strings that container ":". As a result
strings like "prefix:1.2" which would have been quoted as "prefix\:1.2"
end up becoming "prefix" instead causing loss of information and
incorrect CPEs being generated. As a result in such cases, we remove out
strings containing ":" in any part entirely for now. This is similar
to the way we were handling CPE filtering in the past with http urls as
vendor strings

3. Add special handling for version which contain ":" due to epochs in
debian and rpm. In this case, we strip out the parts before ":" i.e.
the epoch and only output the actual function. This ensures we are not
discarding valid version strings due to pt #.2.

In the future we should look at moving to a more spec compliant cpe
parsing library to avoid such shenanigans.

* Remove WFNize for input strings

WFNize seems to not be part of the standard as per
https://pkg.go.dev/github.com/facebookincubator/nvdtools@v0.1.4/wfn#WFNize
and seems to have bugs/issues with encode/decode cycles, so I am
just removing it at this point and relying on the CPE regex to filter
out invalid CPEs for now.
