CVSS: 5.3EPSS: 0%CPEs: 3EXPL: 0CVE-2023-45284 – Incorrect detection of reserved device names on Windows in path/filepath
https://notcve.org/view.php?id=CVE-2023-45284
On Windows, The IsLocal function does not correctly detect reserved device names in some cases. Reserved names followed by spaces, such as "COM1 ", and reserved names "COM" and "LPT" followed by superscript 1, 2, or 3, are incorrectly reported as local. With fix, IsLocal now correctly reports these names as non-local. En Windows, la función IsLocal no detecta correctamente los nombres de dispositivos reservados en algunos casos. Los nombres reservados seguidos de espacios, como "COM1", y los nombres reservados "COM" y "LPT" seguidos del superíndice 1, 2 o 3 se informan incorrectamente como locales. • https://go.dev/cl/540277 https://go.dev/issue/63713 https://groups.google.com/g/golang-announce/c/4tU8LZfBFkY https://pkg.go.dev/vuln/GO-2023-2186 •

The filepath package does not recognize paths with a \??\ prefix as special. On Windows, a path beginning with \??\ is a Root Local Device path equivalent to a path beginning with \\?\. • http://www.openwall.com/lists/oss-security/2023/12/05/2 https://go.dev/cl/540277 https://go.dev/cl/541175 https://go.dev/issue/63713 https://go.dev/issue/64028 https://groups.google.com/g/golang-announce/c/4tU8LZfBFkY https://groups.google.com/g/golang-dev/c/6ypN5EjibjM/m/KmLVYH_uAgAJ https://pkg.go.dev/vuln/GO-2023-2185 https://security.netapp.com/advisory/ntap-20231214-0008 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 0CVE-2023-39325 – HTTP/2 rapid reset can cause excessive work in net/http
https://notcve.org/view.php?id=CVE-2023-39325
A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. • https://go.dev/cl/534215 https://go.dev/cl/534235 https://go.dev/issue/63417 https://groups.google.com/g/golang-announce/c/iNNxDTCjZvo/m/UDd7VKQuAAAJ https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3OVW5V2DM5K5IC3H7O42YDUGNJ74J35O https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3SZN67IL7HMGMNAVLOTIXLIHUDXZK4LH https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3WJ4QVX2AMUJ2F2S27POOAHRC4K3CHU4 https: • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 81%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.1EPSS: 0%CPEs: 5EXPL: 0CVE-2023-39323 – Arbitrary code execution during build via line directives in cmd/go
https://notcve.org/view.php?id=CVE-2023-39323
Line directives ("//line") can be used to bypass the restrictions on "//go:cgo_" directives, allowing blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution of arbitrary code when running "go build". The line directive requires the absolute path of the file in which the directive lives, which makes exploiting this issue significantly more complex. Las directivas de línea ("//line") se pueden utilizar para evitar las restricciones de las directivas "//go:cgo_", permitiendo que se pasen indicadores bloqueados del enlazador y del compilador durante la compilación. Esto puede provocar la ejecución inesperada de código arbitrario al ejecutar "go build". • https://go.dev/cl/533215 https://go.dev/issue/63211 https://groups.google.com/g/golang-announce/c/XBa1oHDevAo https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/CLB4TW7KALB3EEQWNWCN7OUIWWVWWCG2 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/KSEGD2IWKNUO3DWY4KQGUQM5BISRWHQE https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XFOIBB4YFICHDM7IBOP7PWXW3FX4HLL2 https://pkg.go.dev/vuln/GO-2023-2095 https: •
