Comment 9 Jan Pazdziora 2023-07-25 15:17:47 UTC

while doing review of the Vulnerability Assessment report of RHEL 8.6 for the purpose of Common Criteria certification, we came across this CVE-2020-12243. The CVE page https://access.redhat.com/security/cve/cve-2020-12243 lists RHEL 8 as Not affected.

Could a Statement be added to that CVE page that RHEL 8 is not affected because it does not ship slapd, similar to https://access.redhat.com/security/cve/cve-2020-36221?

Thank you, Jan
