Currently flag cvesInRecord is set to false if all CVEs are ignored or patched. This is inconsistent as it shows false if a CVE was fixed via patch and true if this CVE was fixed by upgrade. In both cases the CVE is valid and was fixed. As I understand this flag, it should say if any CVE exists for particular component's product (regardless of how this CVE is handled) and can be used to validate if a product is correctly set. Note that skipping ignored CVEs may make sense in some cases, as ignored may mean that NVD DB is wrong, but in many cases it is ignored for other reasons. Further patch can be done to evaluate ignore subtype but that would be against my understanding of this flag as described above.

# This class is used to check recipes against public CVEs.
|
|
#
|
|
# In order to use this class just inherit the class in the
|
|
# local.conf file and it will add the cve_check task for
|
|
# every recipe. The task can be used per recipe, per image,
|
|
# or using the special cases "world" and "universe". The
|
|
# cve_check task will print a warning for every unpatched
|
|
# CVE found and generate a file in the recipe WORKDIR/cve
|
|
# directory. If an image is build it will generate a report
|
|
# in DEPLOY_DIR_IMAGE for all the packages used.
|
|
#
|
|
# Example:
|
|
# bitbake -c cve_check openssl
|
|
# bitbake core-image-sato
|
|
# bitbake -k -c cve_check universe
|

# The product name that the CVE database uses defaults to BPN, but may need to

# be overriden per recipe (for example tiff.bb sets CVE_PRODUCT=libtiff).
