This update was imported from the SUSE:SLE-12:Update update project.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:0878 advisory.

    The golang packages provide the Go programming language compiler.

    The following packages have been upgraded to a later upstream version: golang (1.9.4). (BZ#1479095,     BZ#1499827)

    Security Fix(es):

    * golang: arbitrary code execution during go get or go get -d (CVE-2017-15041)

    * golang: smtp.PlainAuth susceptible to man-in-the-middle password harvesting (CVE-2017-15042)

    * golang: arbitrary code execution during go get via C compiler options (CVE-2018-6574)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update of the go package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Go before 1.8.7, Go 1.9.x before 1.9.4, and Go 1.10 pre-releases before Go 1.10rc2 allow go get remote     command execution during source code build, by leveraging the gcc or clang plugin feature, because
    -fplugin= and -plugin= arguments were not blocked. (CVE-2018-6574)

Note that Nessus relies on the presence of the package as reported by the vendor.

- Security fix for CVE-2018-6574

  - Rebase to latest point release

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A vulnerability was discovered in the implementation of the P-521 and P-384 elliptic curves, which could result in denial of service and in some cases key recovery.

In addition this update fixes two vulnerabilities in 'go get', which could result in the execution of arbitrary shell commands.

Arbitrary code execution during go get or go get -d

Go before 1.8.4 and 1.9.x before 1.9.1 allows 'go get' remote command execution. Using custom domains, it is possible to arrange things so that example.com/pkg1 points to a Subversion repository but example.com/pkg1/pkg2 points to a Git repository. If the Subversion repository includes a Git checkout in its pkg2 directory and some other work is done to ensure the proper ordering of operations, 'go get' can be tricked into reusing this Git checkout for the fetch of code from pkg2. If the Subversion repository's Git checkout has malicious commands in .git/hooks/, they will execute on the system running 'go get.'(CVE-2017-15041)

smtp.PlainAuth susceptible to man-in-the-middle password harvesting

An unintended cleartext issue exists in Go before 1.8.4 and 1.9.x before 1.9.1. RFC 4954 requires that, during SMTP, the PLAIN auth scheme must only be used on network connections secured with TLS. The original implementation of smtp.PlainAuth in Go 1.0 enforced this requirement, and it was documented to do so. In 2013, upstream issue #5184, this was changed so that the server may decide whether PLAIN is acceptable. The result is that if you set up a man-in-the-middle SMTP server that doesn't advertise STARTTLS and does advertise that PLAIN auth is OK, the smtp.PlainAuth implementation sends the username and password.(CVE-2017-15042)

Arbitrary code execution during 'go get' via C compiler options

An arbitrary command execution flaw was found in the way Go's 'go get' command handled gcc and clang sensitive options during the build. A remote attacker capable of hosting malicious repositories could potentially use this flaw to cause arbitrary command execution on the client side.(CVE-2018-6574)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has golang packages installed that are affected by multiple vulnerabilities:

  - 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)

  - An arbitrary command execution flaw was found in the way     Go's go get command handled gcc and clang sensitive     options during the build. A remote attacker capable of     hosting malicious repositories could potentially use     this flaw to cause arbitrary command execution on the     client side. (CVE-2018-6574)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2018-2885:01 advisory.

    * golang: arbitrary code execution during go get or go get -d (CVE-2017-15041)
    * golang: smtp.PlainAuth susceptible to man-in-the-middle password harvesting (CVE-2017-15042)
    * golang: arbitrary code execution during go get via C compiler options (CVE-2018-6574)

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Go before 1.13.13 and 1.14.x before 1.14.5 has a data     race in some net/http servers, as demonstrated by the     httputil.ReverseProxy Handler, because it reads a     request body and writes a response at the same     time.(CVE-2020-15586)

  - Go before 1.8.7, Go 1.9.x before 1.9.4, and Go 1.10     pre-releases before Go 1.10rc2 allow 'go get' remote     command execution during source code build, by     leveraging the gcc or clang plugin feature, because
    -fplugin= and -plugin= arguments were not     blocked.(CVE-2018-6574)
