CVSS: 5.9EPSS: 0%CPEs: 2EXPL: 0CVE-2017-15042 – golang: smtp.PlainAuth susceptible to man-in-the-middle password harvesting
https://notcve.org/view.php?id=CVE-2017-15042
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. • http://www.securityfocus.com/bid/101197 https://access.redhat.com/errata/RHSA-2017:3463 https://access.redhat.com/errata/RHSA-2018:0878 https://github.com/golang/go/issues/22134 https://golang.org/cl/68023 https://golang.org/cl/68210 https://groups.google.com/d/msg/golang-dev/RinSE3EiJBI/kYL7zb07AgAJ https://security.gentoo.org/glsa/201710-23 https://access.redhat.com/security/cve/CVE-2017-15042 https://bugzilla.redhat.com/show_bug.cgi?id=1498867 • CWE-300: Channel Accessible by Non-Endpoint CWE-319: Cleartext Transmission of Sensitive Information •
CVSS: 9.8EPSS: 5%CPEs: 11EXPL: 0CVE-2017-15041 – golang: arbitrary code execution during "go get" or "go get -d"
https://notcve.org/view.php?id=CVE-2017-15041
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." Go, en sus versiones 1.8.4 y versiones 1.9.x anteriores a la 1.9.1, permite que se ejecuten comandos "go get" de manera remota. • http://www.securityfocus.com/bid/101196 https://access.redhat.com/errata/RHSA-2017:3463 https://access.redhat.com/errata/RHSA-2018:0878 https://github.com/golang/go/issues/22125 https://golang.org/cl/68022 https://golang.org/cl/68190 https://groups.google.com/d/msg/golang-dev/RinSE3EiJBI/kYL7zb07AgAJ https://lists.debian.org/debian-lts-announce/2021/03/msg00014.html https://lists.debian.org/debian-lts-announce/2021/03/msg00015.html https://security.gentoo.org/glsa •

https://notcve.org/view.php?id=CVE-2017-1000098
The net/http package's Request.ParseMultipartForm method starts writing to temporary files once the request body size surpasses the given "maxMemory" limit. It was possible for an attacker to generate a multipart request crafted such that the server ran out of file descriptors. El método Request.ParseMultipartForm del paquete net/http empieza a escribir en archivos temporales una vez que el tamaño del cuerpo de la petición sobrepase el límite "maxMemory" establecido. Un atacante podría generar un petición multipart manipulada para que el servidor se quede sin descriptores de archivo. • https://golang.org/cl/30410 https://golang.org/issue/17965 https://groups.google.com/forum/#%21msg/golang-dev/4NdLzS8sls8/uIz8QlnIBQAJ https://access.redhat.com/security/cve/CVE-2017-1000098 https://bugzilla.redhat.com/show_bug.cgi?id=1401985 • CWE-769: DEPRECATED: Uncontrolled File Descriptor Consumption •

On Darwin, user's trust preferences for root certificates were not honored. If the user had a root certificate loaded in their Keychain that was explicitly not trusted, a Go program would still verify a connection using that root certificate. En Darwin, no se verifican las preferencias de confianza del usuario para certificados root. Si el usuario tiene un certificado root cargado en su Keychain que se ha definido explícitamente como no fiable, un programa Go podría aun verificar una conexión utilizando ese certificado root. • https://github.com/golang/go/issues/18141 https://go-review.googlesource.com/c/33721 https://groups.google.com/forum/#%21msg/golang-dev/4NdLzS8sls8/uIz8QlnIBQAJ • CWE-295: Improper Certificate Validation •
CVSS: 5.9EPSS: 0%CPEs: 6EXPL: 0CVE-2017-8932 – golang: Elliptic curves carry propagation issue in x86-64 P-256
https://notcve.org/view.php?id=CVE-2017-8932
A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries. Un error en la implementación de la biblioteca estándar ScalarMult de curve P-256 para arquitecturas amd64 en Go anterior a versión 1.7.6 y 1.8.x anterior a versión 1.8.2, causa resultados incorrectos para ser generados por puntos de entrada específicos. Se puede montar un ataque adaptativo para extraer progresivamente la entrada scalar hacia ScalarMult mediante el envío de puntos creados y observando fallos para la salida correcta derivada. • http://lists.opensuse.org/opensuse-updates/2017-06/msg00079.html http://lists.opensuse.org/opensuse-updates/2017-06/msg00080.html https://access.redhat.com/errata/RHSA-2017:1859 https://bugzilla.redhat.com/show_bug.cgi?id=1455191 https://github.com/golang/go/commit/9294fa2749ffee7edbbb817a0ef9fe633136fa9c https://github.com/golang/go/issues/20040 https://go-review.googlesource.com/c/41070 https://groups.google.com/d/msg/golang-announce/B5ww0iFt1_Q/TgUFJV14BgAJ https://lists.fedoraproject.org&# • CWE-682: Incorrect Calculation •
