high Nessus Plugin ID 176670

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by a vulnerability as referenced in the USN-6112-2 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
