Title:	Huawei EulerOS: Security Advisory for nss-softokn (EulerOS-SA-2020-1651)
Summary:	The remote host is missing an update for the Huawei EulerOS 'nss-softokn' package(s) announced via the EulerOS-SA-2020-1651 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'nss-softokn' package(s) announced via the EulerOS-SA-2020-1651 advisory. Vulnerability Insight: 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) 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) Affected Software/OS: 'nss-softokn' package(s) on Huawei EulerOS V2.0SP2. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
