Thank you for the link.

Unfortunately, I'm not sure about the way I should interpret it and how it replies to my previous statements.

According to me, this should match my case:

Platform: Red Hat Enterprise Linux 8
Package: httpd:2.4
State: Fixed
Errata: RHSA-2020:4751
Release Date: November 4, 2020

Image

knowing that

CentOS version | RHEL base | Kernel | CentOS release date | RHEL release date | Delay (days)
8.3-2011 | 8.3 | 4.18.0-240 | 2020-12-07 | 2020-11-03 | 34

Image

but I probably misunderstand something.

After updating my system to Centos 8.3, the latest available httpd package is still 2.4.37 and the related changelog hasn't changed either.

https://access.redhat.com/errata/RHSA-2020:4751 says it's fixed in 2.4.37-30 and that is the current version listed by dnf list httpd on CentOS 8.3.

Thank you for your feedback.

Indeed the listed package is 2.4.37-30.module_el8.3.0+561+97fdbbcc linked to source httpd-2.4.37-30.module_el8.3.0+561+97fdbbcc.src.rpm, which seems to correspond to the one mentioned in the errata (httpd-2.4.37-30.module+el8.3.0+7001+0766b9e7.src.rpm).

I couldn't find the meaning of the bold numbers (561 & 7001) but I assume it makes the distinction between Red Hat and CentOS.

I'm still puzzling over the following: is it then a mistake/a lack that CVE-2018-17189 is not mentioned in the changelog of version 2.4.37-30?

Anyone know how to fix this one ?

I can't seem to find a recent update for this bug in Centos8.

moderate: CVE-2019-10097 mod_remoteip: Stack buffer overflow and NULL pointer dereference (CVE-2019-10097)
When mod_remoteip was configured to use a trusted intermediary proxy server using the "PROXY" protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients.
