The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3327 advisory.

    Package        : nss     Version        : 2:3.42.1-1+deb10u6     CVE ID         : CVE-2020-6829 CVE-2020-12400 CVE-2020-12401 CVE-2020-12403                      CVE-2023-0767

    Multiple security vulnerabilities have been discovered in nss, the Network     Security Service libraries.

    CVE-2020-6829

        When performing EC scalar point multiplication, the wNAF point         multiplication algorithm was used; which leaked partial information about         the nonce used during signature generation. Given an electro-magnetic trace         of a few signature generations, the private key could have been computed.

    CVE-2020-12400

        When converting coordinates from projective to affine, the modular         inversion was not performed in constant time, resulting in a possible         timing-based side channel attack.

    CVE-2020-12401

        During ECDSA signature generation, padding applied in the nonce designed to         ensure constant-time scalar multiplication was removed, resulting in         variable-time execution dependent on secret data.

    CVE-2020-12403

        A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS.
        When using multi-part Chacha20, it could cause out-of-bounds reads.
        This issue was fixed by explicitly disabling multi-part ChaCha20         (which was not functioning correctly) and strictly enforcing tag length.

    CVE-2023-0767

        Christian Holler discovered that incorrect handling of PKCS 12 Safe Bag         attributes may result in execution of arbitrary code if a specially crafted         PKCS 12 certificate bundle is processed.

    For Debian 10 buster, these problems have been fixed in version     2:3.42.1-1+deb10u6.

    We recommend that you upgrade your nss packages.
