Descriptions

Code injection in the go command with cgo before Go 1.14.12 and Go 1.15.5 allows arbitrary code execution at build time via a malicious unquoted symbol name in a linked object file.

Go versiones anteriores a 1.14.12 y versiones 1.15.x anteriores a 1.15.5, permite una Inyección de Código

An input validation vulnerability was found in Go. From a generated go file (from the cgo tool), it is possible to modify symbols within that object file and specify code. This flaw allows an attacker to create a repository that includes malicious pre-built object files that could execute arbitrary code when downloaded and run via `go get` or `go build` while building a Go project. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Red Hat OpenShift Serverless Client kn CLI is delivered as an RPM package for installation on RHEL platforms, and as binaries for non-Linux platforms. Red Hat OpenShift Serverless Client kn 1.12.0 provides a CLI to interact with Red Hat OpenShift Serverless 1.12.0, and includes security and bug fixes and enhancements. For more information, see the release notes listed in the References section. Issues addressed include code execution and cross site scripting vulnerabilities.
