CVSS: 7.5EPSS: 83%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: 9.0EPSS: 32%CPEs: 47EXPL: 21CVE-2019-14287 – sudo 1.8.27 - Security Bypass
https://notcve.org/view.php?id=CVE-2019-14287
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command. En Sudo anteriores a 1.8.28, un atacante con acceso a una cuenta Runas ALL sudoer puede omitir ciertas listas negras de políticas y módulos PAM de sesión, y puede causar un registro incorrecto, mediante la invocación sudo con un ID de usuario creado. Por ejemplo, esto permite la omisión de la configuración root y el registro USER= para un comando "sudo -u \#$((0xffffffff))". • https://www.exploit-db.com/exploits/47502 https://github.com/n0w4n/CVE-2019-14287 https://github.com/shallvhack/Sudo-Security-Bypass-CVE-2019-14287 https://github.com/CMNatic/Dockerized-CVE-2019-14287 https://github.com/axax002/sudo-vulnerability-CVE-2019-14287 https://github.com/N3rdyN3xus/CVE-2019-14287 https://github.com/DewmiApsara/CVE-2019-14287 https://github.com/MariliaMeira/CVE-2019-14287 https://github.com/edsonjt81/CVE-2019-14287- https://github.com/SachinthaDeSilva-cmd& • CWE-267: Privilege Defined With Unsafe Actions CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2019-14816
There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento del búfer en la región heap de la memoria en el kernel, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0204&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 5.9EPSS: 1%CPEs: 42EXPL: 0CVE-2018-10237 – guava: Unbounded memory allocation in AtomicDoubleArray and CompoundOrdering classes allow remote attackers to cause a denial of service
https://notcve.org/view.php?id=CVE-2018-10237
Unbounded memory allocation in Google Guava 11.0 through 24.x before 24.1.1 allows remote attackers to conduct denial of service attacks against servers that depend on this library and deserialize attacker-provided data, because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable. Asignación de memoria sin restringir en Google Guava 11.0 hasta las versiones 24.x anteriores a la 24.1.1 permite que los atacantes remotos realicen ataques de denegación de servicio (DoS) contra servidores que dependen de esta librería y que deserialicen datos proporcionados por dichos atacantes debido a que la clase AtomicDoubleArray (cuando se serializa con serialización Java) y la clase CompoundOrdering (cuando se serializa con serialización GWT) realiza una asignación sin comprobar adecuadamente lo que ha enviado un cliente y si el tamaño de los datos es razonable. A vulnerability was found in Guava where the AtomicDoubleArray and CompoundOrdering classes were found to allocate memory based on size fields sent by the client without validation. A crafted message could cause the server to consume all available memory or crash leading to a denial of service. • http://www.securitytracker.com/id/1041707 https://access.redhat.com/errata/RHSA-2018:2423 https://access.redhat.com/errata/RHSA-2018:2424 https://access.redhat.com/errata/RHSA-2018:2425 https://access.redhat.com/errata/RHSA-2018:2428 https://access.redhat.com/errata/RHSA-2018:2598 https://access.redhat.com/errata/RHSA-2018:2643 https://access.redhat.com/errata/RHSA-2018:2740 https://access.redhat.com/errata/RHSA-2018:2741 https://access.redhat.com/errata/RHSA-2018:274 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-770: Allocation of Resources Without Limits or Throttling •
