https://notcve.org/view.php?id=CVE-2021-3905
A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments. Se ha encontrado una pérdida de memoria en Open vSwitch (OVS) durante el procesamiento de la fragmentación IP en el espacio de usuario. Un atacante podría usar este fallo para agotar potencialmente la memoria disponible al seguir enviando fragmentos de paquetes. • https://access.redhat.com/security/cve/CVE-2021-3905 https://bugzilla.redhat.com/show_bug.cgi?id=2019692 https://github.com/openvswitch/ovs-issues/issues/226 https://github.com/openvswitch/ovs/commit/803ed12e31b0377c37d7aa8c94b3b92f2081e349 https://security.gentoo.org/glsa/202311-16 https://ubuntu.com/security/CVE-2021-3905 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2019-14818 – dpdk: possible memory leak leads to denial of service
https://notcve.org/view.php?id=CVE-2019-14818
A flaw was found in all dpdk version 17.x.x before 17.11.8, 16.x.x before 16.11.10, 18.x.x before 18.11.4 and 19.x.x before 19.08.1 where a malicious master, or a container with access to vhost_user socket, can send specially crafted VRING_SET_NUM messages, resulting in a memory leak including file descriptors. This flaw could lead to a denial of service condition. Se encontró un fallo en todas las versiones de dpdk 17.xx anteriores a 17.11.8, versiones 16.xx anteriores a 16.11.10, versiones 18.xx anteriores a 18.11.4 y versiones 19.xx anteriores a 19.08.1, donde un maestro malicioso o un contenedor con acceso al socket vhost_user, puede enviar mensajes de VRING_SET_NUM especialmente diseñados, resultando en una pérdida de memoria incluyendo descriptores de archivo. Este fallo podría conllevar a una condición de denegación de servicio. A flaw was found in dpdk where a malicious master, or a container with access to vhost_user socket, can send specially crafted VRING_SET_NUM messages, resulting in a memory leak including file descriptors. • https://access.redhat.com/errata/RHSA-2020:0165 https://access.redhat.com/errata/RHSA-2020:0166 https://access.redhat.com/errata/RHSA-2020:0168 https://access.redhat.com/errata/RHSA-2020:0171 https://access.redhat.com/errata/RHSA-2020:0172 https://bugs.dpdk.org/show_bug.cgi?id=363 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14818 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ULJ3C7OVBOEVDGSHYC3VCLSUHANGTFFP https://access.redhat& • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2018-1059 – dpdk: Information exposure in unchecked guest physical to host virtual address translations
https://notcve.org/view.php?id=CVE-2018-1059
The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical Addresses to Host Virtual Addresses translations. This may lead to a malicious guest exposing vhost-user backend process memory. All versions before 18.02.1 are vulnerable. La interfaz vhost de usuario de DPDK no verifica que el rango físico invitado solicitado esté mapeado y sea contiguo al realizar traducciones de direcciones físicas de invitado a direcciones virtuales del host. Esto podría conducir a que un invitado malicioso exponga la memoria del proceso del backend del usuario vhost. • https://access.redhat.com/errata/RHSA-2018:1267 https://access.redhat.com/errata/RHSA-2018:2038 https://access.redhat.com/errata/RHSA-2018:2102 https://access.redhat.com/errata/RHSA-2018:2524 https://access.redhat.com/security/cve/cve-2018-1059 https://bugzilla.redhat.com/show_bug.cgi?id=1544298 https://usn.ubuntu.com/3642-1 https://usn.ubuntu.com/3642-2 https://access.redhat.com/security/cve/CVE-2018-1059 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
