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 •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-2879 – Unbounded memory consumption when reading headers in archive/tar
https://notcve.org/view.php?id=CVE-2022-2879
Reader.Read does not set a limit on the maximum size of file headers. A maliciously crafted archive could cause Read to allocate unbounded amounts of memory, potentially causing resource exhaustion or panics. After fix, Reader.Read limits the maximum size of header blocks to 1 MiB. Reader.Read no establece un límite en el tamaño máximo de los encabezados de los archivos. Un archivo diseñado de forma maliciosa podía causar que Read asignara cantidades ilimitadas de memoria, causando potencialmente el agotamiento de los recursos o el pánico. • https://go.dev/cl/439355 https://go.dev/issue/54853 https://groups.google.com/g/golang-announce/c/xtuG5faxtaU https://pkg.go.dev/vuln/GO-2022-1037 https://security.gentoo.org/glsa/202311-09 https://access.redhat.com/security/cve/CVE-2022-2879 https://bugzilla.redhat.com/show_bug.cgi?id=2132867 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 1CVE-2022-2880 – Incorrect sanitization of forwarded query parameters in net/http/httputil
https://notcve.org/view.php?id=CVE-2022-2880
Requests forwarded by ReverseProxy include the raw query parameters from the inbound request, including unparsable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy forwards a parameter with an unparsable value. After fix, ReverseProxy sanitizes the query parameters in the forwarded query when the outbound request's Form field is set after the ReverseProxy. Director function returns, indicating that the proxy has parsed the query parameters. Proxies which do not parse query parameters continue to forward the original query parameters unchanged. • https://go.dev/cl/432976 https://go.dev/issue/54663 https://groups.google.com/g/golang-announce/c/xtuG5faxtaU https://pkg.go.dev/vuln/GO-2022-1038 https://security.gentoo.org/glsa/202311-09 https://access.redhat.com/security/cve/CVE-2022-2880 https://bugzilla.redhat.com/show_bug.cgi?id=2132868 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
