There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking. The
    Crypt::PK::RSA, Crypt::PK::DSA, Crypt::PK::DH, Crypt::PK::ECC, Crypt::PK::Ed25519 and Crypt::PK::X25519
    modules seed a per-object PRNG state in their constructors and reuse it without fork detection. A
    Crypt::PK::* object created before `fork()` shares byte-identical PRNG state with every child process, and
    any randomized operation they perform can produce identical output, including key generation. Two ECDSA or
    DSA signatures from different processes are enough to recover the signing private key through nonce-reuse
    key recovery. This affects preforking services such as the Starman web server, where a Crypt::PK::* object
    loaded at startup is inherited by every worker process. (CVE-2026-41564)

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-3e1f671a17 advisory.

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

  - CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking. The     Crypt::PK::RSA, Crypt::PK::DSA, Crypt::PK::DH, Crypt::PK::ECC, Crypt::PK::Ed25519 and Crypt::PK::X25519     modules seed a per-object PRNG state in their constructors and reuse it without fork detection.

This affects preforking services such as the Starman web server, where a Crypt::PK::* object     loaded at startup is inherited by every worker process. (CVE-2026-41564)

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-2026-bc5090f99b advisory.
