CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2022-41725 – Excessive resource consumption in mime/multipart
https://notcve.org/view.php?id=CVE-2022-41725
A denial of service is possible from excessive resource consumption in net/http and mime/multipart. Multipart form parsing with mime/multipart.Reader.ReadForm can consume largely unlimited amounts of memory and disk files. This also affects form parsing in the net/http package with the Request methods FormFile, FormValue, ParseMultipartForm, and PostFormValue. ReadForm takes a maxMemory parameter, and is documented as storing "up to maxMemory bytes +10MB (reserved for non-file parts) in memory". File parts which cannot be stored in memory are stored on disk in temporary files. • https://go.dev/cl/468124 https://go.dev/issue/58006 https://groups.google.com/g/golang-announce/c/V0aBFqaFs_E https://pkg.go.dev/vuln/GO-2023-1569 https://security.gentoo.org/glsa/202311-09 https://access.redhat.com/security/cve/CVE-2022-41725 https://bugzilla.redhat.com/show_bug.cgi?id=2178488 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-41722 – Path traversal on Windows in path/filepath
https://notcve.org/view.php?id=CVE-2022-41722
A path traversal vulnerability exists in filepath.Clean on Windows. On Windows, the filepath.Clean function could transform an invalid path such as "a/../c:/b" into the valid path "c:\b". This transformation of a relative (if invalid) path into an absolute path could enable a directory traversal attack. After fix, the filepath.Clean function transforms this path into the relative (but still invalid) path ". • https://go.dev/cl/468123 https://go.dev/issue/57274 https://groups.google.com/g/golang-announce/c/V0aBFqaFs_E https://pkg.go.dev/vuln/GO-2023-1568 https://access.redhat.com/security/cve/CVE-2022-41722 https://bugzilla.redhat.com/show_bug.cgi?id=2203008 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 5.3EPSS: 0%CPEs: 5EXPL: 0CVE-2022-41717 – Excessive memory growth in net/http and golang.org/x/net/http2
https://notcve.org/view.php?id=CVE-2022-41717
An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection. Un atacante puede provocar un crecimiento excesivo de la memoria en un servidor Go que acepta solicitudes HTTP/2. Las conexiones del servidor HTTP/2 contienen un caché de claves de encabezado HTTP enviadas por el cliente. • https://go.dev/cl/455635 https://go.dev/cl/455717 https://go.dev/issue/56350 https://groups.google.com/g/golang-announce/c/L_3rmdT0BMU/m/yZDrXjIiBQAJ https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4BUK2ZIAGCULOOYDNH25JPU6JBES5NF2 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4SBIUECMLNC572P23DDOKJNKPJVX26SP https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/56B2FFESRYYP6IY2AZ3UWXLWKZ5IYZN4 https • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-41720 – Restricted file access on Windows in os and net/http
https://notcve.org/view.php?id=CVE-2022-41720
On Windows, restricted files can be accessed via os.DirFS and http.Dir. The os.DirFS function and http.Dir type provide access to a tree of files rooted at a given directory. These functions permit access to Windows device files under that root. For example, os.DirFS("C:/tmp").Open("COM1") opens the COM1 device. Both os.DirFS and http.Dir only provide read-only filesystem access. • https://go.dev/cl/455716 https://go.dev/issue/56694 https://groups.google.com/g/golang-announce/c/L_3rmdT0BMU/m/yZDrXjIiBQAJ https://pkg.go.dev/vuln/GO-2022-1143 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-41716 – Unsanitized NUL in environment variables on Windows in syscall and os/exec
https://notcve.org/view.php?id=CVE-2022-41716
Due to unsanitized NUL values, attackers may be able to maliciously set environment variables on Windows. In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" sets the variables "A=B" and "C=D". Debido a valores NUL no sanitizados, los atacantes pueden configurar variables de entorno de forma maliciosa en Windows. • https://go.dev/cl/446916 https://go.dev/issue/56284 https://groups.google.com/g/golang-announce/c/mbHY1UY3BaM/m/hSpmRzk-AgAJ https://pkg.go.dev/vuln/GO-2022-1095 •
