CVSS: 6.1EPSS: 0%CPEs: 15EXPL: 0CVE-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 •

CVSS: 7.5EPSS: 11%CPEs: 10EXPL: 0CVE-2017-7539 – Qemu: qemu-nbd crashes due to undefined I/O coroutine
https://notcve.org/view.php?id=CVE-2017-7539
An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. Se ha detectado un fallo de aserción en Qemu en versiones anteriores a la 2.10.1 en la negociación de conexión inicial de los servidores de NBD (Network Block Device) en el que la corrutina I/O no estaba definida. Esto podría provocar el cierre inesperado del servidor qemu-nbd si un cliente envía datos no esperados durante la negociación de la conexión. • http://www.openwall.com/lists/oss-security/2017/07/21/4 http://www.securityfocus.com/bid/99944 https://access.redhat.com/errata/RHSA-2017:2628 https://access.redhat.com/errata/RHSA-2017:3466 https://access.redhat.com/errata/RHSA-2017:3470 https://access.redhat.com/errata/RHSA-2017:3471 https://access.redhat.com/errata/RHSA-2017:3472 https://access.redhat.com/errata/RHSA-2017:3473 https://access.redhat.com/errata/RHSA-2017:3474 https://bugzilla.redhat.com/show_b • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2017-10664
qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt. qemu-nbd en QEMU (Quick Emulator) no ignora la señal SIGPIPE, lo que permite a atacantes remotos provocar una denegación de servicio desconectando el proceso durante un intento de respuesta de servidor a cliente. Quick Emulator (QEMU) built with the Network Block Device (NBD) Server support is vulnerable to a crash via a SIGPIPE signal. The crash can occur if a client aborts a connection due to any failure during negotiation or read operation. A remote user/process could use this flaw to crash the qemu-nbd server resulting in a Denial of Service (DoS). • http://www.debian.org/security/2017/dsa-3920 http://www.openwall.com/lists/oss-security/2017/06/29/1 http://www.securityfocus.com/bid/99513 https://access.redhat.com/errata/RHSA-2017:2390 https://access.redhat.com/errata/RHSA-2017:2445 https://access.redhat.com/errata/RHSA-2017:3466 https://access.redhat.com/errata/RHSA-2017:3470 https://access.redhat.com/errata/RHSA-2017:3471 https://access.redhat.com/errata/RHSA-2017:3472 https://access.redhat.com/errata/RH • CWE-248: Uncaught Exception •

An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. • http://ubuntu.com/usn/usn-3289-1 http://www.openwall.com/lists/oss-security/2017/04/21/1 http://www.securityfocus.com/bid/102129 http://www.securityfocus.com/bid/97955 https://access.redhat.com/errata/RHSA-2017:0980 https://access.redhat.com/errata/RHSA-2017:0981 https://access.redhat.com/errata/RHSA-2017:0982 https://access.redhat.com/errata/RHSA-2017:0983 https://access.redhat.com/errata/RHSA-2017:0984 https://access.redhat.com/errata/RHSA-2017:0988 https • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
