The following updates has been released for Debian GNU/Linux 8 LTS:

DLA 1840-1: golang-go.crypto security update
DLA 1841-1: gpac security update

DLA 1840-1: golang-go.crypto security update

Package : golang-go.crypto
Version : 0.0~hg190-1+deb8u1
CVE ID : CVE-2019-11840

A flaw was found in the amd64 implementation of salsa20. 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.

For Debian 8 "Jessie", this problem has been fixed in version
0.0~hg190-1+deb8u1.

obfs4proxy has been rebuilt as version 0.0.3-2+deb8u1.

We recommend that you upgrade your golang-golang-x-crypto-dev
and obfs4proxy packages, and rebuild any software using
golang-golang-x-crypto-dev.
