USN-6112-1 fixed vulnerabilities in Perl. This update provides the corresponding updates for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 22.10, and Ubuntu 23.04.

Original advisory details:

It was discovered that Perl was not properly verifying TLS certificates when using CPAN together with HTTP::Tiny to download modules over HTTPS. If a remote attacker were able to intercept communications, this flaw could potentially be used to install altered modules.
