CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-27918 – golang: encoding/xml: infinite loop when using xml.NewTokenDecoder with a custom TokenReader
https://notcve.org/view.php?id=CVE-2021-27918
encoding/xml in Go before 1.15.9 and 1.16.x before 1.16.1 has an infinite loop if a custom TokenReader (for xml.NewTokenDecoder) returns EOF in the middle of an element. This can occur in the Decode, DecodeElement, or Skip method. encoding/xml en Go versiones anteriores a 1.15.9 y versiones 1.16.x anteriores a 1.16.1, presenta un bucle infinito si un TokenReader personalizado (para xml.NewTokenDecoder) devuelve EOF en medio de un elemento. Esto puede ocurrir en el método Decode, DecodeElement o Skip An infinite loop vulnerability was found in golang. If an application defines a custom token parser initializing with `xml.NewTokenDecoder` it is possible for the parsing loop to never return. An attacker could potentially craft a malicious XML document which has an XML element with `EOF` within it, causing the parsing application to endlessly loop, resulting in a Denial of Service (DoS). • https://groups.google.com/g/golang-announce/c/MfiLYjG-RAw https://security.gentoo.org/glsa/202208-02 https://access.redhat.com/security/cve/CVE-2021-27918 https://bugzilla.redhat.com/show_bug.cgi?id=1937901 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2021-3114
In Go before 1.14.14 and 1.15.x before 1.15.7, crypto/elliptic/p224.go can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field. En Go versiones anteriores a 1.14.14 y versiones 1.15.x anteriores a 1.15.7, en el archivo crypto/elliptic/p224.go puede generar salidas incorrectas, relacionadas con un subdesbordamiento de la extremidad más baja durante la reducción completa final en el campo P-224 A flaw detected in golang: crypto/elliptic, in which P-224 keys as generated can return incorrect inputs, reducing the strength of the cryptography. The highest threat from this vulnerability is confidentiality and integrity. • https://github.com/golang/go/commit/d95ca9138026cbe40e0857d76a81a16d03230871 https://groups.google.com/g/golang-announce/c/mperVMGa98w https://lists.debian.org/debian-lts-announce/2021/03/msg00014.html https://lists.debian.org/debian-lts-announce/2021/03/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YWAYJGXWC232SG3UR3TR574E6BP3OSQQ https://security.gentoo.org/glsa/202208-02 https://security.netapp.com/advisory/ntap-20210219-0001 https://www.debian.or • CWE-682: Incorrect Calculation •
CVSS: 7.5EPSS: 1%CPEs: 6EXPL: 0CVE-2021-3115 – golang: cmd/go: packages using cgo can cause arbitrary code execution at build time
https://notcve.org/view.php?id=CVE-2021-3115
Go before 1.14.14 and 1.15.x before 1.15.7 on Windows is vulnerable to Command Injection and remote code execution when using the "go get" command to fetch modules that make use of cgo (for example, cgo can execute a gcc program from an untrusted download). Go versiones anteriores a 1.14.14 y versiones 1.15. x anteriores a 1.15.7 en Windows, es vulnerable a una inyección de comandos y una ejecución de código remota cuando es usado el comando "go get" para buscar módulos que hacen uso de cgo (por ejemplo, cgo puede ejecutar un programa gcc desde una descarga que no es confiable) A flaw was found in golang: cmd/go, in which Go can execute arbitrary commands at build time when cgo is in use on Windows OS. On Linux/Unix, only users who have "." listed explicitly in their PATH variable are affected. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://blog.golang.org/path-security https://groups.google.com/g/golang-announce/c/mperVMGa98w https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YWAYJGXWC232SG3UR3TR574E6BP3OSQQ https://security.gentoo.org/glsa/202208-02 https://security.netapp.com/advisory/ntap-20210219-0001 https://access.redhat.com/security/cve/CVE-2021-3115 https://bugzilla.redhat.com/show_bug.cgi?id=1918761 • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-427: Uncontrolled Search Path Element •
