Missing fixes for CVE-2021-40438 and CVE-2021-26691 in the versions of
httpd, as shipped in Red Hat Enterprise Linux 8.5.0, causes a security
regression compared to the versions shipped in Red Hat Enterprise Linux
8.4. A user who installs or updates to Red Hat Enterprise Linux 8.5.0 would
be vulnerable to the mentioned CVEs, even if they were properly fixed in
Red Hat Enterprise Linux 8.4. CVE-2021-20325 was assigned to that Red Hat
specific security regression and it does not affect the upstream versions
of httpd.

Notes

Author Note
alexmurray This vulnerability is specific to RHEL only and does not affect apache2 as packaged in Ubuntu.
