Patrick Williams | c0f7c04 | 2017-02-23 20:41:17 -0600 | [diff] [blame] | 7 | # This class is used to check recipes against public CVEs. |
| 8 | # |
| 9 | # In order to use this class just inherit the class in the |
| 10 | # local.conf file and it will add the cve_check task for |
| 11 | # every recipe. The task can be used per recipe, per image, |
| 12 | # or using the special cases "world" and "universe". The |
| 13 | # cve_check task will print a warning for every unpatched |
| 14 | # CVE found and generate a file in the recipe WORKDIR/cve |
| 15 | # directory. If an image is build it will generate a report |
| 16 | # in DEPLOY_DIR_IMAGE for all the packages used. |
| 17 | # |
| 18 | # Example: |
| 19 | # bitbake -c cve_check openssl |
| 20 | # bitbake core-image-sato |
| 21 | # bitbake -k -c cve_check universe |
| 22 | # |
| 23 | # DISCLAIMER |
| 24 | # |
| 25 | # This class/tool is meant to be used as support and not |
| 26 | # the only method to check against CVEs. Running this tool |
| 27 | # doesn't guarantee your packages are free of CVEs. |
