https://notcve.org/view.php?id=CVE-2020-28362
Go before 1.14.12 and 1.15.x before 1.15.4 allows Denial of Service. Go versiones anteriores a 1.14.12 y versiones 1.15.x anteriores a 1.15.4, permite una Denegación de Servicio A flaw was found in the math/big package of Go's standard library that causes a denial of service. Applications written in Go that use math/big via cryptographic packages, including crypto/rsa and crypto/x509, are vulnerable and can potentially cause panic via a crafted certificate chain. The highest threat from this vulnerability is to system availability. • https://groups.google.com/g/golang-nuts/c/c-ssaaS7RMI https://lists.apache.org/thread.html/rd02e75766cd333a0df417588460f5e4477060633000bfe94955851fd%40%3Cissues.trafficcontrol.apache.org%3E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2W4COUPL3YVTZ6RTEIT6LPBDJUFF3VSP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F3ZSHGNTJWCWYAKY5OLZS2XQQYHSXSUO https://security.netapp.com/advisory/ntap-20201202-0004 https://www.arista.com/en/support/advisories-notices/ • CWE-295: Improper Certificate Validation •
CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2020-28366 – Arbitrary code execution in go command with cgo in cmd/go and cmd/cgo
https://notcve.org/view.php?id=CVE-2020-28366
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. • https://go.dev/cl/269658 https://go.dev/issue/42559 https://go.googlesource.com/go/+/062e0e5ce6df339dc26732438ad771f73dbf2292 https://groups.google.com/g/golang-announce/c/NpBGTTmKzpM https://pkg.go.dev/vuln/GO-2022-0475 https://access.redhat.com/security/cve/CVE-2020-28366 https://bugzilla.redhat.com/show_bug.cgi?id=1897643 • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •

https://notcve.org/view.php?id=CVE-2020-28367
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 malicious gcc flags specified via a #cgo directive. La inyección de código en el comando go con cgo antes de Go 1.14.12 y Go 1.15.5 permite la ejecución de código arbitrario en tiempo de compilación a través de banderas gcc maliciosas especificadas a través de una directiva #cgo An input validation vulnerability was found in Go. If cgo is specified in a Go file, it is possible to bypass the validation of arguments to the gcc compiler. This flaw allows an attacker to create a malicious repository that can execute arbitrary code when downloaded and run via `go get` or `go build` while building a Go project.
