SCA: security update for golang.org/x/crypto (GHSA-r5c5-pr8j-pfp7)

medium Tenable Cloud Security Plugin ID 418501

Description

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

 - An issue was discovered in the supplementary Go cryptography library, golang.org/x/crypto, before
 v0.0.0-20190320223903-b7391e95e576. A flaw was found in the amd64 implementation of the
 golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa packages. If more than 256 GiB of
 keystream is generated, or if the counter otherwise grows greater than 32 bits, the amd64 implementation
 will first generate incorrect output, and then cycle back to previously generated keystream. Repeated
 keystream bytes can lead to loss of confidentiality in encryption applications, or to predictability in
 CSPRNG applications. (CVE-2019-11840)
