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 •

In Undertow before versions 7.1.2.CR1, 7.1.2.GA it was found that the fix for CVE-2016-4993 was incomplete and Undertow web server is vulnerable to the injection of arbitrary HTTP headers, and also response splitting, due to insufficient sanitization and validation of user input before the input is used as part of an HTTP header value. En Undertow, en versiones anteriores a la 7.1.2.CR1, 7.1.2.GA, se descubrió que la solución para CVE-2016-4993 no estaba completa. Por lo tanto, el servidor web de Undertow es vulnerable a la inyección de cabeceras HTTP arbitrarias y también a la separación de respuestas, debido al saneamiento y validación insuficientes de entradas de usuario antes de que se empleen como parte de un valor de cabecera HTTP.

https://notcve.org/view.php?id=CVE-2018-8778
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure. En Ruby, en versiones anteriores a la 2.2.10, versiones 2.3.x anteriores a la 2.3.7, versiones 2.4.x anteriores a la 2.4.4, versiones 2.5.x anteriores a la 2.5.1 y la versión 2.6.0-preview1, un atacante que controla el formato de desempaquetado (similar a las vulnerabilidades de cadena de formato) puede desencadenar una sublectura de búfer en el método String#unpack. Esto resulta en una gran divulgación de información controlada. A integer underflow was found in the way String#unpack decodes the unpacking format. An attacker, able to control the unpack format, could use this flaw to disclose arbitrary parts of the application's memory. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00036.html http://www.securityfocus.com/bid/103693 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2018:3729 https://access.redhat.com/errata/RHSA-2018:3730 https://access.redhat.com/errata/RHSA-2018:3731 https://access.redhat.com/errata/RHSA-2019:2028 https://lists.debian.org/debian-lts-announce/2018/04/msg00023.html https://lists.debian.org/debian-lts-announce/2018/04/msg00024.html& • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-134: Use of Externally-Controlled Format String •
