The version of nspr installed on the remote host is prior to 4.21.0-1.43. The version of nss installed on the remote host is prior to 3.44.0-7.84. The version of nss-softokn installed on the remote host is prior to 3.44.0-8.44. The version of nss-util installed on the remote host is prior to 3.44.0-4.56. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1355 advisory.

    A heap-based buffer overflow was found in the NSC_EncryptUpdate() function in Mozilla nss. A remote     attacker could trigger this flaw via SRTP encrypt or decrypt operations, to execute arbitrary code with     the permissions of the user running the application (compiled with nss). While the attack complexity is     high, the impact to confidentiality, integrity, and availability are high as well. (CVE-2019-11745)

    A cached side channel attack during handshakes using RSA encryption could allow for the decryption of     encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack)     and affects all NSS versions prior to NSS 3.41. (CVE-2018-12404)

    Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly     sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox     < 68, and Thunderbird < 60.8. (CVE-2019-11729)

    Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA     signatures that can be mitigated through the use of blinding during the signing process in the
    _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP.
    To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual     machine on the same physical host. (CVE-2018-0495)

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

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