From the first analysis:

CVE-2017-7867 is not in in 58.1 but it is in 58.2
CVE-2017-7868 is in each release and should be fixed in 59.1

Debian is listing the same changeset (https://ssl.icu-project.org/trac/changeset/39671) for both vulnerabilities. But your posting indicates that each vulnerability requires an own patch. Can you please clarify where your analysis is based on? Thanks.

Scratch the previous question, another dupe.
