Alpine: multiple libgcrypt packages: security update to 1.8.3-r0

medium Tenable Cloud Security Plugin ID 424025

Description

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

 - 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)
