Hi Daniel In Ubuntu we generally do not upgrade to new package versions to fix security issues but instead backport the individual fixes. As such you should not expect to see say apache 2.4.56 in Ubuntu 23.04. Instead we just add the minimal change needed to fix the vulnerability on top of the existing 2.4.55 version.
Regarding these two CVEs in question, you can see the status for each of these vulnerabilities in Ubuntu at https://ubuntu.com/security/CVE-2023-27522 and https://ubuntu.com/security/CVE-2023-25690 respectively. Both have already been patched and updates released back in March of this year. For more details on how package updates work in Ubuntu, I recommend taking a look at https://ubuntu.com/blog/ubuntu-updates-releases-and-repositories-explained Thanks, Alex On Thu, 2023-09-07 at 17:25:27 +0000, Daniel Johnston wrote: > Hello, > > I was wondering on when you plan to upgrade Apache from 2.4.55 to at least > 2.4.56 to address the vulnerabilities with Apache? > We have been checking weekly for a number of months now. > Changes with Apache 2.4.56 > > *) SECURITY: CVE-2023-27522: Apache HTTP Server: mod_proxy_uwsgi > HTTP response splitting (cve.mitre.org) > HTTP Response Smuggling vulnerability in Apache HTTP Server via > mod_proxy_uwsgi.
