In Go before 1.13.13 and 1.14.x before 1.14.5, Certificate.Verify may lack a check on the VerifyOptions.KeyUsages EKU requirements (if VerifyOptions.Roots equals nil and the installation is on Windows). Thus, X.509 certificate verification is incomplete. En Go versiones anteriores a 1.13.13 y versiones 1.14.x anteriores a 1.14.5, Certificate.Verify puede carecer de una comprobación en los requisitos VerifyOptions.KeyUsages EKU (si VerifyOptions.Roots es igual a cero y la instalación está en Windows).

https://notcve.org/view.php?id=CVE-2020-15586
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. Go versiones anteriores a 1.13.13 y versiones 1.14.x anteriores a 1.14.5, presenta una carrera de datos en algunos servidores net/http, como es demostrado por el Manejador httputil.ReverseProxy, porque lee un cuerpo de petición y escribe una respuesta al mismo tiempo A flaw was found Go's net/http package. Servers using ReverseProxy from net/http in the Go standard library are vulnerable to a data race that results in a denial of service. The highest threat from this vulnerability is to system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00077.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00082.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00030.html https://groups.google.com/forum/#%21topic/golang-announce/XZNfaiwgt2w https://groups.google.com/forum/#%21topic/golang-announce/f2c5bqrGH_g https://lists.debian.org/debian-lts-announce/2020/11/msg00037& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling. Go versiones anteriores a 1.12.10 y versiones 1.13.x anteriores a 1.13.1, permitir el Trafico No Autorizado de Peticiones HTTP. It was discovered that net/http (through net/textproto) in golang does not correctly interpret HTTP requests where an HTTP header contains spaces before the colon. This could be abused by an attacker to smuggle HTTP requests when a proxy or a firewall is placed behind a server implemented in Go or to filter bypasses depending on the specific network configuration. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00044.html https://access.redhat.com/errata/RHSA-2020:0101 https://access.redhat.com/errata/RHSA-2020:0329 https://access.redhat.com/errata/RHSA-2020:0652 https://github.com/golang/go/issues/34540 https://groups.google.com/forum/#%21msg/golang-announce/cszieYyuL9Q/g4Z7pKaqAgAJ https://lists.debian.org/debian-lts-announce/2021/03/msg00014.html https&# • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 9.8EPSS: 3%CPEs: 3EXPL: 1CVE-2019-14809 – golang: malformed hosts in URLs leads to authorization bypass
https://notcve.org/view.php?id=CVE-2019-14809
net/url in Go before 1.11.13 and 1.12.x before 1.12.8 mishandles malformed hosts in URLs, leading to an authorization bypass in some applications. This is related to a Host field with a suffix appearing in neither Hostname() nor Port(), and is related to a non-numeric port number. For example, an attacker can compose a crafted javascript:// URL that results in a hostname of google.com. net / url in Go antes del 1.11.13 y 1.12.x antes del 1.12.8 maneja mal los hosts mal formados en las URL, lo que lleva a una omisión de autorización en algunas aplicaciones. Esto está relacionado con un campo Host con un sufijo que no aparece en Hostname () ni Port (), y está relacionado con un número de puerto no numérico. Por ejemplo, un atacante puede componer un javascript creado: // URL que da como resultado un nombre de host de google.com. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00038.html https://access.redhat.com/errata/RHSA-2019:3433 https://github.com/golang/go/issues/29098 https://groups.google.com/forum/ • CWE-285: Improper Authorization •
