Alpine: multiple mbedtls packages: security update to 2.16.6-r0

medium Tenable Cloud Security Plugin ID 424179

Description

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

 - An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get
 precise enough side-channel measurements can recover the long-term ECDSA private key by (1) reconstructing
 the projective coordinate of the result of scalar multiplication by exploiting side channels in the
 conversion to affine coordinates; (2) using an attack described by Naccache, Smart, and Stern in 2003 to
 recover a few bits of the ephemeral scalar from those projective coordinates via several measurements; and
 (3) using a lattice attack to get from there to the long-term ECDSA private key used for the signatures.
 Typically an attacker would have sufficient access when attacking an SGX enclave and controlling the
 untrusted OS. (CVE-2020-10932)
