  • Workaroundperl-CPAN-0:2.18-402.el8_10.noarch as a component of Red Hat Enterprise Linux AppStream (v. 8)redhat_csaf

    This issue can be mitigated by configuring perl-CPAN to only use trusted CPAN mirrors (www.cpan.org or cpan.metacpan.org) and use HTTPS for communication with CPAN servers. If you already have a cpan configured, the list of configured mirrors can be viewed by running the `cpan` command without any argument and entering the following command on the cpan command's prompt: ``` o conf urllist ``` Ensure that the URL list only includes trusted mirrors and that https:// scheme is used for all URLs. A different set of mirrors can be configured using the following commands (these examples show how to configure one or more mirrors, only one of the commands should be used): ``` o conf urllist https://www.cpan.org o conf urllist https://www.cpan.org https://cpan.metacpan.org ``` After changing configuration, the following command must be used to save the configuration: ``` o conf commit ```
