It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-072 advisory.

  - CPAN 2.28 allows Signature Verification Bypass. (CVE-2020-16156)

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

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - perl: corruption of intermediate language state of compiled regular expression due to integer overflow     leads to DoS (CVE-2020-10878)

  - Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular     expression quantifiers have an integer overflow. (CVE-2020-10543)

  - regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of     recursive S_study_chunk calls. (CVE-2020-12723)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3926 advisory.

    Package        : perl     Version        : 5.32.1-4+deb11u4     CVE ID         : CVE-2020-16156 CVE-2023-31484     Debian Bug     : 1015985 1035109

    Vulnerabilities were found in Perl's CPAN.pm, which could lead CPAN     clients to install malicious modules.

    CVE-2020-16156

        Stig Palmquist discovered that an attacker can prepend checksums for         modified packages to the beginning of CHECKSUMS files, before the         cleartext PGP headers, resulting in signature verification bypass.

        CPAN.pm has been updated so that when configured to validate the         signature on CHECKSUMS, it will refuse to install a tarball if the         associated CHECKSUMS file isn't signed.  The gpg(1) executable is         required in order to validate signatures.

    CVE-2023-31484

        Stig Palmquist discovered that CPAN::HTTP::Client did not verify         X.509 certificates in the HTTP::Tiny call, which could allows an         attacker to MITM the connection with the CPAN mirror.

        CPAN::HTTP::Client now enables the `verify_SSL` flag.  HTTPS mirrors         therefore require a valid certificate.  The identity of the default         mirror https://cpan.org can be verified after installing the         'ca-certificates' package.

    For Debian 11 bullseye, these problems have been fixed in version     5.32.1-4+deb11u4.

    We recommend that you upgrade your perl packages.
