@Maintainers affected version is 9.21, could you confirm if 9.17 is affected?

CVE-2017-7206:

Fixed in 11.11 and 12.2 releases.  Not fixed in 9.21 (dying branch?  Last release over a year a go).

9.x branch remains unfixed.


CVE-2017-7208:

Fixed in 12.2.  Code is not present in previous versions so no vulnerability.
Comment 3 Aaron Bauman (RETIRED) gentoo-dev 2019-03-26 16:09:43 UTC 
Tree is free of vulnerable versions. Marking as <12.3 since it is latest stable.
