My customer has an Ubuntu server "22.04.4 LTS (GNU/Linux 6.5.0-1022-azure x86_64)" running Apache with mod-perl. Installed Perl version is 5.34. Recently I was asked by business owner to update the Perl to 5.40 due to some vulnerabilities found in 5.34. Unfortunately I'm rather a developer and can only do simplest administrative operations on Ubuntu so this is something completely new for me. I started from "sudo apt update" and then "apt-list--upgradable". There are some packages but only "libdpkg-perl" seems having some relation to Perl. According to its description that is not what I'm looking for. I found a list of modules which were installed on that machine. Some from them look like related to web site:
- apache2
- perl
- libapache2-mod-perl2
- libapache2-mod-perl2-dev
- libgd-dev
- libgd-graph-perl
- libapr1-dev
- libssl-dev
- libxml2-dev
- libxml-libxml-perl
- libxml-libxslt-perl
- libapache2-request-perl
- cpanminus
All these modules are not listed as having upgrades. So, how to upgrade Perl? Is it possible at all without updating the whole system? Thank you in advance!
