Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Meaning k = r mod n. The division used during the reduction estimates a factor q_e by dividing the upper two digits (a digit having e.g. a size of 8 byte) of r by the upper digit of n and then decrements q_e in a loop until it has the correct size. Observing the number of times q_e is decremented through a control-flow revealing side-channel reveals a bias in the most significant bits of k. Depending on the curve this is either a negligible bias or a significant bias large enough to reconstruct k with lattice reduction methods. For SECP160R1, e.g., we find a bias of 15 bits.

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 8fbe81f7-6eb5-11ef-b7bd-00505632d232 advisory.

    Netatalk release reports:
    WolfSSL 5.7.0 (included in netatalk) includes multiple security vulnerabilities.

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

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

The version of netatalk installed on the remote host is prior to 3.2.8. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2024-253-01 advisory.

    New netatalk packages are available for Slackware 15.0 and -current to fix security issues.

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