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."

Several vulnerabilities were discovered in the Go programming language. An attacker could trigger a denial of service (DoS), bypasss access control, and execute arbitrary code on the developer's computer.

CVE-2017-15041

Go 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-2018-16873

The 'go get' command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go package, as it may treat the parent directory as a Git repository root, containing malicious configuration.

CVE-2018-16874

The 'go get' command is vulnerable to directory traversal when executed with the import path of a malicious Go package which contains curly braces (both '{' and '}' characters). The attacker can cause an arbitrary filesystem write, which can lead to code execution.

CVE-2019-9741

In net/http, CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the second argument to http.NewRequest with \r\n followed by an HTTP header or a Redis command.

CVE-2019-16276

Go allows HTTP Request Smuggling.

CVE-2019-17596

Go can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates.

CVE-2021-3114

crypto/elliptic/p224.go can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field.

For Debian 9 stretch, these problems have been fixed in version 1.8.1-1+deb9u3.

We recommend that you upgrade your golang-1.8 packages.

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.

An update of the go package has been released.

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 following packages have been upgraded to a later upstream version:
golang (1.9.4).

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)

Additional Changes :

An update for golang is now available for Red Hat Enterprise Linux 7.
