https://notcve.org/view.php?id=CVE-2021-33195
Go before 1.15.13 and 1.16.x before 1.16.5 has functions for DNS lookups that do not validate replies from DNS servers, and thus a return value may contain an unsafe injection (e.g., XSS) that does not conform to the RFC1035 format. Go versiones anteriores a 1.15.13 y versiones 1.16.x anteriores a 1.16.5 tiene funciones para las búsquedas de DNS que no validan las respuestas de los servidores DNS, y por lo tanto un valor de retorno puede contener una inyección insegura (por ejemplo, XSS) que no se ajusta al formato RFC1035 A flaw was found in Go. The LookupCNAME, LookupSRV, LookupMX, LookupNS, and LookupAddr functions in the net package and methods on the Resolver type, may return arbitrary values retrieved from DNS, allowing injection of unexpected contents. The highest threat from this vulnerability is to integrity. • https://groups.google.com/g/golang-announce https://groups.google.com/g/golang-announce/c/RgCMkAEQjSI https://security.gentoo.org/glsa/202208-02 https://security.netapp.com/advisory/ntap-20210902-0005 https://access.redhat.com/security/cve/CVE-2021-33195 https://bugzilla.redhat.com/show_bug.cgi?id=1989564 • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 6.5EPSS: 0%CPEs: 8EXPL: 0CVE-2021-34558 – golang: crypto/tls: certificate of wrong type is causing TLS client to panic
https://notcve.org/view.php?id=CVE-2021-34558
The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic. El paquete crypto/tls de Go versiones hasta 1.16.5, no afirma apropiadamente que el tipo de clave pública en un certificado X.509 coincida con el tipo esperado cuando se hace un intercambio de claves basado en RSA, permitiendo a un servidor TLS malicioso causar el pánico en un cliente TLS A flaw was found in golang. A panic can be triggered by an attacker in a privileged network position without access to the server certificate's private key, as long as a trusted ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with Config.InsecureSkipVerify. Clients that disable all TLS_RSA cipher suites (that is, TLS 1.0–1.2 cipher suites without ECDHE), as well as TLS 1.3-only clients, are unaffected. • https://golang.org/doc/devel/release#go1.16.minor https://groups.google.com/g/golang-announce https://groups.google.com/g/golang-announce/c/n9FxMelZGAQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3BA7MFVXRBEKRTLSLYDICTYCGEMK2HZ7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3XBQUFVI5TMV4KMKI7GKA223LHGPQISE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6BTC3JQUASFN5U2XA4UZIGAPZQBD5JSS https:/&# • CWE-20: Improper Input Validation CWE-295: Improper Certificate Validation •

https://notcve.org/view.php?id=CVE-2021-33196
In archive/zip in Go before 1.15.13 and 1.16.x before 1.16.5, a crafted file count (in an archive's header) can cause a NewReader or OpenReader panic. En archive/zip en Go versiones anteriores a 1.15.13 y versiones 1.16.x anteriores a 1.16.5, un recuento de archivos crafteado (en la cabecera de un archivo) puede causar un pánico en NewReader u OpenReader. A vulnerability was found in archive/zip of the Go standard library. Applications written in Go can panic or potentially exhaust system memory when parsing malformed ZIP files. • https://groups.google.com/g/golang-announce https://groups.google.com/g/golang-announce/c/RgCMkAEQjSI https://lists.debian.org/debian-lts-announce/2022/01/msg00016.html https://lists.debian.org/debian-lts-announce/2022/01/msg00017.html https://lists.debian.org/debian-lts-announce/2023/04/msg00021.html https://security.gentoo.org/glsa/202208-02 https://access.redhat.com/security/cve/CVE-2021-33196 https://bugzilla.redhat.com/show_bug.cgi?id=1965503 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •

net/http in Go before 1.15.12 and 1.16.x before 1.16.4 allows remote attackers to cause a denial of service (panic) via a large header to ReadRequest or ReadResponse. Server, Transport, and Client can each be affected in some configurations. net/http en Go versiones anteriores a 1.15.12 y versiones 1.16.x anteriores a 1.16.4, permite a atacantes remotos causar una denegación de servicio (pánico) por medio de un encabezado grande en los parámetros ReadRequest o ReadResponse. El Servidor, el Transporte y el Cliente pueden estar afectados en algunas configuraciones A vulnerability was detected in net/http of the Go standard library when parsing very large HTTP header values, causing a crash and subsequent denial of service. This vulnerability affects both clients and servers written in Go, however, servers are only vulnerable if the value of MaxHeaderBytes has been increased from the default. • https://github.com/golang/go/issues/45710 https://groups.google.com/g/golang-announce/c/cu9SP4eSXMc https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ISRZZ6NY5R2TBYE72KZFOCO25TEUQTBF https://security.gentoo.org/glsa/202208-02 https://access.redhat.com/security/cve/CVE-2021-31525 https://bugzilla.redhat.com/show_bug.cgi?id=1958341 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-674: Uncontrolled Recursion •
