Descriptions

Using go get to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git://" protocol if the module is unavailable via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE is not set for said module. This only affects users who are not using the module proxy and are fetching modules directly (i.e. GOPROXY=off).

El uso de go get para buscar un módulo con el sufijo ".git" puede recurrir inesperadamente al protocolo inseguro "git://" si el módulo no está disponible a través de "https://" y "git+ssh://" seguros, protocolos, incluso si GOINSECURE no está configurado para dicho módulo. Esto sólo afecta a los usuarios que no utilizan el proxy del módulo y están obteniendo módulos directamente (es decir, GOPROXY = desactivado).

A flaw was found in the Golang package cmd/go. This issue permits the fallback to insecure "git://" if trying to fetch a .git module that has no "https://" or "git+ssh://" available.

Takeshi Kaneko discovered that Go did not properly handle comments and special tags in the script context of html/template module. An attacker could possibly use this issue to inject Javascript code and perform a cross site scripting attack. This issue only affected Go 1.20 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 23.04. It was discovered that Go did not properly validate the "//go:cgo_" directives during compilation. An attacker could possibly use this issue to inject arbitrary code during compile time.
