CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 1CVE-2017-13672 – QEMU: vga: OOB read access during display update
https://notcve.org/view.php?id=CVE-2017-13672
QEMU (aka Quick Emulator), when built with the VGA display emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors involving display update. QEMU (también conocido como Quick Emulator), cuando se integra con soporte para emulador de pantalla VGA, permite que usuarios con privilegios de sistema operativo invitado local provoquen una denegación de servicio (lectura fuera de límites y bloqueo del proceso QEMU) mediante vectores relacionados con la actualización de pantalla. An out-of-bounds read access issue was found in the VGA display emulator built into the Quick emulator (QEMU). It could occur while reading VGA memory to update graphics display. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of service situation. • https://github.com/DavidBuchanan314/CVE-2017-13672 http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html http://www.debian.org/security/2017/dsa-3991 http://www.openwall.com/lists/oss-security/2017/08/30/3 http://www.securityfocus.com/bid/100540 https://access.redhat.com/errata/RHSA-2018:0816 https://access.redhat.com/errata/RHSA-2018:1104 https://access.redhat.com/errata/RHSA-2018:1113 https://access.redhat.com/errata/RHSA-2018:2162 https://bugzi • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 1%CPEs: 2EXPL: 0CVE-2017-13711 – QEMU: Slirp: use-after-free when sending response
https://notcve.org/view.php?id=CVE-2017-13711
Use-after-free vulnerability in the sofree function in slirp/socket.c in QEMU (aka Quick Emulator) allows attackers to cause a denial of service (QEMU instance crash) by leveraging failure to properly clear ifq_so from pending packets. Una vulnerabilidad de uso después de liberación de memoria (use-after-free) en la función sofree en slirp/socket.c en QEMU (también conocido como Quick Emulator) permite que atacantes remotos provoquen una denegación de servicio (bloqueo de la instancia QEMU) aprovechando el error a la hora de eliminar correctamente ifq_so de los paquetes pendientes. A use-after-free issue was found in the Slirp networking implementation of the Quick emulator (QEMU). It occurs when a Socket referenced from multiple packets is freed while responding to a message. A user/process could use this flaw to crash the QEMU process on the host resulting in denial of service. • http://www.debian.org/security/2017/dsa-3991 http://www.openwall.com/lists/oss-security/2017/08/29/6 http://www.securityfocus.com/bid/100534 https://access.redhat.com/errata/RHSA-2018:0816 https://access.redhat.com/errata/RHSA-2018:1104 https://access.redhat.com/errata/RHSA-2018:1113 https://bugzilla.redhat.com/show_bug.cgi?id=1486400 https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg05201.html https://access.redhat.com/security/cve/CVE-2017-13711 • CWE-416: Use After Free •

QEMU (aka Quick Emulator), when built with the IDE disk and CD/DVD-ROM Emulator support, allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) by flushing an empty CDROM device drive. QEMU (también conocido como Quick Emulator), cuando se integra con el disco IDE y soporte para CD/DVD-ROM Emulator, permite que usuarios con privilegios de sistema operativo invitado local provoquen una denegación de servicio (desreferencia de puntero NULL y bloqueo del proceso QEMU) al vaciar una unidad de dispositivo CDROM vacía. • http://www.debian.org/security/2017/dsa-3991 http://www.openwall.com/lists/oss-security/2017/08/21/2 http://www.securityfocus.com/bid/100451 https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg01850.html • CWE-476: NULL Pointer Dereference •

The dhcp_decode function in slirp/bootp.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) via a crafted DHCP options string. La función dhcp_decode en el archivo slirp/bootp.c en QEMU (conocido como Quick Emulator), permite a los usuarios de sistemas operativos invitados locales causar una denegación de servicio (lectura fuera de límites y bloqueo del proceso QEMU) por medio de una cadena de opciones DHCP creada. • http://www.debian.org/security/2017/dsa-3925 http://www.openwall.com/lists/oss-security/2017/07/19/2 http://www.securityfocus.com/bid/99923 https://bugzilla.redhat.com/show_bug.cgi?id=1472611 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://lists.gnu.org/archive/html/qemu-devel/2017-07/msg05001.html • CWE-125: Out-of-bounds Read •
