Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. This issue affects operating systems where "/dev/urandom'" is unavailable. In that case, Crypt::CBC will fallback to use the insecure rand() function.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand() function as the default source of     entropy, which is not cryptographically secure, for cryptographic functions. This issue affects operating     systems where /dev/urandom' is unavailable. In that case, Crypt::CBC will fallback to use the insecure     rand() function. (CVE-2025-2814)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 42 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2025-f7bc7b789f advisory.

    This update, to the current upstream release version, includes a fix to source random numbers using the     `Crypt::URandom` module rather than trying to read `/dev/urandom` and falling back to Perl's insecure     `rand()` function if `/dev/urandom` is not usable (CVE-2025-2814).



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

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the cd7f969e-6cb4-11f0-97c4-40b034429ecf advisory.
