CVSS: 10.0EPSS: 3%CPEs: 19EXPL: 0CVE-2016-0749 – spice: heap-based memory corruption within smartcard handling
https://notcve.org/view.php?id=CVE-2016-0749
The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow. La interacción smartcard en SPICE permite a atacantes remotos provocar un denegación de servicio (caída del proceso QEMU-KVM) o ejecutar, posiblemente, un código arbitrario a través de véctores relacionados con conectarse con un invitado VM, lo que ejecuta un desbordamiento de bufer basado en memoria dinámica. A memory allocation flaw, leading to a heap-based buffer overflow, was found in spice's smartcard interaction, which runs under the QEMU-KVM context on the host. A user connecting to a guest VM using spice could potentially use this flaw to crash the QEMU-KVM process or execute arbitrary code with the privileges of the host's QEMU-KVM process. • http://lists.opensuse.org/opensuse-updates/2016-07/msg00003.html http://lists.opensuse.org/opensuse-updates/2016-07/msg00004.html http://www.debian.org/security/2016/dsa-3596 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.ubuntu.com/usn/USN-3014-1 https://access.redhat.com/errata/RHSA-2016:1204 https://access.redhat.com/errata/RHSA-2016:1205 https://security.gentoo.org/glsa/201606-05 https://access.redhat.com/security/cve/CVE-2016 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
CVSS: 7.8EPSS: 0%CPEs: 31EXPL: 0CVE-2016-5126 – Qemu: block: iscsi: buffer overflow in iscsi_aio_ioctl
https://notcve.org/view.php?id=CVE-2016-5126
Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call. Desbordamiento de buffer basado en memoria dinámica en la función iscsi_aio_ioctl en block/iscsi.c en QEMU permite a usuarios locales del SO invitado provocar una denegación de servicio (caída del proceso QEMU) o posiblemente ejecutar código arbitrario a través de una llamada iSCSI ioctl I/O asíncrona manipulada. Quick Emulator(QEMU) built with the Block driver for iSCSI images support (virtio-blk) is vulnerable to a heap-based buffer overflow issue. The flaw could occur while processing iSCSI asynchronous I/O ioctl(2) calls. A user inside a guest could exploit this flaw to crash the QEMU process resulting in denial of service, or potentially leverage it to execute arbitrary code with QEMU-process privileges on the host. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=a6b3167fa0e825aebb5a7cd8b437b6d41584a196 http://rhn.redhat.com/errata/RHSA-2016-1606.html http://rhn.redhat.com/errata/RHSA-2016-1607.html http://rhn.redhat.com/errata/RHSA-2016-1653.html http://rhn.redhat.com/errata/RHSA-2016-1654.html http://rhn.redhat.com/errata/RHSA-2016-1655.html http://rhn.redhat.com/errata/RHSA-2016-1756.html http://rhn.redhat.com/errata/RHSA-2016-1763.html http://www.openwall.com/lists/oss-secu • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2016-3698
libndp before 1.6, as used in NetworkManager, does not properly validate the origin of Neighbor Discovery Protocol (NDP) messages, which allows remote attackers to conduct man-in-the-middle attacks or cause a denial of service (network connectivity disruption) by advertising a node as a router from a non-local network. libndp en versiones anteriores a 1.6, como es usado en NetworkManager, no valida correctamente el origen de los mensajes Neighbor Discovery Protocol (NDP), lo que provoca a atacantes remotos llevar a cabo ataques man-in-the-middle o provocar una caída del servicio (interrupción de la conectividad de red) anunciando un nodo como un router de una red no local. It was found that libndp did not properly validate and check the origin of Neighbor Discovery Protocol (NDP) messages. An attacker on a non-local network could use this flaw to advertise a node as a router, allowing them to perform man-in-the-middle attacks on a connecting client, or disrupt the network connectivity of that client. • http://www.debian.org/security/2016/dsa-3581 http://www.openwall.com/lists/oss-security/2016/05/17/9 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.ubuntu.com/usn/USN-2980-1 https://github.com/jpirko/libndp/commit/2af9a55b38b55abbf05fd116ec097d4029115839 https://github.com/jpirko/libndp/commit/a4892df306e0532487f1634ba6d4c6d4bb381c7f https://rhn.redhat.com/errata/RHSA-2016-1086.html https://access.redhat.com/security/cve/CVE-2016-3698 https://bugzill • CWE-20: Improper Input Validation CWE-284: Improper Access Control •
