A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption. Se encontró un problema de corrupción de memoria en DPDK versiones 17.05 y superiores. Este fallo es causado por un truncamiento de enteros en el índice de una carga útil. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=268 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10723 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://usn.ubuntu.com/4362-1 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020&# • CWE-190: Integer Overflow or Wraparound •

A vulnerability was found in DPDK versions 19.11 and above. A malicious container that has direct access to the vhost-user socket can keep sending VHOST_USER_GET_INFLIGHT_FD messages, causing a resource leak (file descriptors and virtual memory), which may result in a denial of service. Se detectó una vulnerabilidad en DPDK versiones 19.11 y superiores. Un contenedor malicioso que presenta acceso directo al socket vhost-user puede seguir enviando mensajes de VHOST_USER_GET_INFLIGHT_FD, causando una filtración de recursos (descriptores de archivos y memoria virtual), lo que puede resultar en una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=271 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10726 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://access.redhat.com/security/cve/CVE-2020-10726 https://bugzilla.redhat.com • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •

A flaw was found in DPDK version 19.11 and above that allows a malicious guest to cause a segmentation fault of the vhost-user backend application running on the host, which could result in a loss of connectivity for the other guests running on that host. This is caused by a missing validity check of the descriptor address in the function `virtio_dev_rx_batch_packed()`. Se detectó un fallo en DPDK versión 19.11 y superior, que permite a un invitado malicioso causar un fallo de segmentación de la aplicación backend vhost-user que se ejecuta en el host, lo que podría resultar en una pérdida de conectividad para los otros invitados ejecutados en ese host. Esto es causado por una falta de comprobación de la validez de la dirección del descriptor en la función "virtio_dev_rx_batch_packed()". • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=270 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10725 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://access.redhat.com/security/cve/CVE-2020-10725 https://bugzilla.redhat.com • CWE-665: Improper Initialization •

A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption. Se encontró una vulnerabilidad en DPDK versiones 18.05 y superiores. Una falta de comprobación en un desbordamiento de enteros en la función vhost_user_set_log_base() podría resultar en un mapa de memoria más pequeño de lo requerido, posiblemente permitiendo una corrupción de la memoria. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=267 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10722 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://usn.ubuntu.com/4362-1 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020&# • CWE-190: Integer Overflow or Wraparound •

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 •
