Red Hat Security Advisory
Synopsis: Moderate: go-toolset-7 and go-toolset-7-golang security and bug fix update
Advisory ID: RHSA-2017:3463-01
Product: Red Hat Developer Tools
Advisory URL: https://access.redhat.com/errata/RHSA-2017:3463
Issue date: 2017-12-14
CVE Names: CVE-2017-15041 CVE-2017-15042
=====================================================================
1. Summary:
An update for go-toolset-7 and go-toolset-7-golang is now available for Red
Hat Developer Tools.
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Developer Tools for Red Hat Enterprise Linux Server (v. 7) – aarch64, noarch, ppc64le, s390x, x86_64
Red Hat Developer Tools for Red Hat Enterprise Linux Workstation (v. 7) – noarch, x86_64
3. Description:
Go Toolset provides the Go programming language tools and libraries. Go is
alternatively known as golang.
Security Fix(es):
* An arbitrary command execution flaw was found in the way Go’s “go get”
command handled the checkout of source code repositories. A remote attacker
capable of hosting malicious repositories could potentially use this flaw
to cause arbitrary command execution on the client side. (CVE-2017-15041)
* It was found that smtp.PlainAuth authentication scheme in Go did not
verify the TLS requirement properly. A remote man-in-the-middle attacker
could potentially use this flaw to sniff SMTP credentials sent by a Go
application. (CVE-2017-15042)
Bug Fix(es):
* Previously, the enable script for the go-toolset-7 Software Collection
incorrectly set the GOPATH environment variable to a directory that
required root permissions for write operations. As a consequence, the go
compiler terminated unexpectedly when performing certain commands. The
enable script has been changed to handle GOPATH correctly, and the
described problem no longer occurs. (BZ#1512013)
