https://notcve.org/view.php?id=CVE-2020-10683
dom4j before 2.0.3 and 2.1.x before 2.1.3 allows external DTDs and External Entities by default, which might enable XXE attacks. However, there is popular external documentation from OWASP showing how to enable the safe, non-default behavior in any application that uses dom4j. dom4j versiones anteriores a 2.0.3 y versiones 2.1.x anteriores a 2.1.3, permite DTDs y External Entities por defecto, lo que podría permitir ataques de tipo XXE. Sin embargo, existe una documentación externa popular de OWASP que muestra cómo habilitar el comportamiento seguro no predeterminado en cualquier aplicación que use dom4j. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00061.html https://bugzilla.redhat.com/show_bug.cgi?id=1694235 https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html https://github.com/dom4j/dom4j/commit/a8228522a99a02146106672a34c104adbda5c658 https://github.com/dom4j/dom4j/commits/version-2.0.3 https://github.com/dom4j/dom4j/issues/87 https://github.com/dom4j/dom4j/releases/tag/version-2.1.3 https://lists.apache.org/thread.html/r51f3f9801058 • CWE-611: Improper Restriction of XML External Entity Reference •

https://notcve.org/view.php?id=CVE-2020-10663
The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent. La gema JSON versiones hasta 2.2.0 para Ruby, como es usado en Ruby versiones 2.4 hasta 2.4.9, versiones 2.5 hasta 2.5.7 y versiones 2.6 hasta 2.6.5, tiene una Vulnerabilidad de Creación de Objetos No Segura. Esto es bastante similar a CVE-2013-0269, pero no se basa en un comportamiento inapropiado garbage-collection dentro de Ruby. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00004.html http://seclists.org/fulldisclosure/2020/Dec/32 https://lists.apache.org/thread.html/r37c0e1807da7ff2bdd028bbe296465a6bbb99e2320dbe661d5d8b33b%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r3b04f4e99a19613f88ae088aa18cd271231a3c79dfff8f5efa8cda61%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r5f17bfca1d6e7f4b33ae978725b2fd62a9f1b3111696eafa9add802d%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r8d2e174230f6d26e16c0 • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •

https://notcve.org/view.php?id=CVE-2020-1983
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service. Una vulnerabilidad de uso de la memoria previamente liberada en la función ip_reass() en el archivo ip_input.c de libslirp versiones 4.2.0 y anteriores permite que paquetes especialmente diseñados causen una denegación de servicio. A use-after-free flaw was found in the SLiRP networking implementation of the QEMU emulator. Specifically, this flaw occurs in the ip_reass() routine while reassembling incoming IP fragments whose combined size is bigger than 65k. This flaw allows an attacker to crash the QEMU process on the host, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00001.html https://gitlab.freedesktop.org/slirp/libslirp/-/commit/9ac0371bb8c0a40f5d9f82a1c25129660e81df04 https://gitlab.freedesktop.org/slirp/libslirp/-/issues/20 https://lists.debian.org/debian-lts-announce/2020/06/msg00032.html https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-416: Use After Free •
