Upstream's solution for the last issue adds a new runtime dependency mlocati/ip-lib ≥1.22
which unfortunately is not in Debian yet.  I can upload it to sid as
part of the PEAR team, but older suites will need another solution.

AFAIK no CVE-ID have been published for these issues.  I just requested some.
