CVE-2023-31484 Perl vulnerability
Title: Perl vulnerability
Summary: Perl could be made to install modules from untrusted sources.
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.
Instructions: In general, a standard system update will make all the necessary changes.

perl: CPAN.pm does not verify TLS certificates when downloading distributions over HTTPS
CPAN.pm before 2.35 does not verify TLS certificates when downloading distributions over HTTPS.
A flaw was found in Perl's CPAN, which doesn't check TLS certificates when downloading content. This happens due to `verify_SSL` missing when suing the `HTTP::Tiny` library during the connection. This may allow an attacker to inject into the network path and perform a Man-In-The-Middle attack, causing confidentiality or integrity issues.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
