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 •

The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. La función tcpmss_mangle_packet en net/netfilter/xt_TCPMSS.c en el kernel de Linux, en versiones anteriores a la 4.11 y en versiones 4.9.x anteriores a la 4.9.36, permite que atacantes remotos provoquen una denegación de servicio (uso de memoria previamente liberada y corrupción de memoria) o, posiblemente, otro tipo de impacto sin especificar aprovechando la presencia de xt_TCPMSS en una acción iptables. The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2638fd0f92d4397884fd991d8f4925cb3f081901 http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00047.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •

Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated. Ansible en versiones anteriores a la 2.3.1.0 y 2.4.0.0 no marca correctamente los resultados del plugin lookup como no seguros. Si un atacante pudiese controlar los resultados de las llamadas lookup(), podrían inyectar cadenas Unicode para que sean analizadas por el sistema de plantillas jinja2, resultando en una ejecución de código. • http://www.securityfocus.com/bid/98492 https://access.redhat.com/errata/RHSA-2017:1244 https://access.redhat.com/errata/RHSA-2017:1334 https://access.redhat.com/errata/RHSA-2017:1476 https://access.redhat.com/errata/RHSA-2017:1499 https://access.redhat.com/errata/RHSA-2017:1599 https://access.redhat.com/errata/RHSA-2017:2524 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-7481 https://github.com/ansible/ansible/commit/ed56f51f185a1ffd7ea57130d260098686fcc7c2 https://lists.deb • CWE-20: Improper Input Validation •

QEMU before 2.0.0 block drivers for CLOOP, QCOW2 version 2 and various other image formats are vulnerable to potential memory corruptions, integer/buffer overflows or crash caused by missing input validations which could allow a remote user to execute arbitrary code on the host with the privileges of the QEMU process.

Qemu before 1.6.2 block diver for the various disk image formats used by Bochs and for the QCOW version 2 format, are vulnerable to a possible crash caused by signed data types or a logic error while creating QCOW2 snapshots, which leads to incorrectly calling update_refcount() routine.
