CVSS: 6.9EPSS: 0%CPEs: 51EXPL: 1CVE-2015-3214 – QEMU - Programmable Interrupt Timer Controller Heap Overflow
https://notcve.org/view.php?id=CVE-2015-3214
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. Vulnerabilidad en pit_ioport_read en i8254.c en el kernel de Linux en versiones anteriores a 2.6.33 y en QEMU en versiones anteriores a 2.3.1, no distingue entre longitudes de lectura y longitudes de escritura, lo que podría permitir a los usuarios invitados del SO ejecutar código arbitrario en el host del SO desencadenando el uso de un índice no válido. An out-of-bounds memory access flaw, leading to memory corruption or possibly an information leak, was found in QEMU's pit_ioport_read() function. A privileged guest user in a QEMU guest, which had QEMU PIT emulation enabled, could potentially, in rare cases, use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. • https://www.exploit-db.com/exploits/37990 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ee73f656a604d5aa9df86a97102e4e462dd79924 http://mirror.linux.org.au/linux/kernel/v2.6/ChangeLog-2.6.33 http://rhn.redhat.com/errata/RHSA-2015-1507.html http://rhn.redhat.com/errata/RHSA-2015-1508.html http://rhn.redhat.com/errata/RHSA-2015-1512.html http://www.debian.org/security/2015/dsa-3348 http://www.openwall.com/lists/oss-security/2015/06/25/7 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 7%CPEs: 36EXPL: 0CVE-2015-3209 – qemu: pcnet: multi-tmd buffer overflow in the tx path
https://notcve.org/view.php?id=CVE-2015-3209
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. Desbordamiento de buffer basado en memoria dinámica en el controlador PCNET en QEMU permite a atacantes remotos ejecutar código arbitrario mediante el envío de un paquete con el juego TXSTATUS_STARTPACKET y posteriormente un paquete manipulado con el juego TXSTATUS_DEVICEOWNS. A flaw was found in the way QEMU's AMD PCnet Ethernet emulation handled multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10698 http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160669.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160677.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2015-3456
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. Floppy Disk Controller (FDC) en QEMU, utilizado en Xen 4.5.x y anteriores y KVM, permite a usuarios locales invitados causar una denegación de servicio (escritura fuera de rango y caída del invitado) o posiblemente ejecutar código arbitrario a través de (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, u otros comandos sin especificar, también conocido como VENOM. An out-of-bounds memory access flaw was found in the way QEMU's virtual Floppy Disk Controller (FDC) handled FIFO buffer access while processing certain FDC commands. A privileged guest user could use this flaw to crash the guest or, potentially, execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest. • https://www.exploit-db.com/exploits/37053 http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=e907746266721f305d67bc0718795fedee2e824c http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10693 http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158072.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00014.html http:/&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2015-1842
The puppet manifests in the Red Hat openstack-puppet-modules package before 2014.2.13-2 uses a default password of CHANGEME for the pcsd daemon, which allows remote attackers to execute arbitrary shell commands via unspecified vectors. Puppet Manifests en el paquete openstack-puppet-modules de Red Hat anterior a 2014.2.13-2 utiliza una contraseño por defecto de CHANGEME para el demonio pcsd, lo que permite a atacantes remotos ejecutar comandos de shell arbitrarios a través de vectores no especificados. It was discovered that the puppet manifests, as provided with the openstack-puppet-modules package, would configure the pcsd daemon with a known default password. If this password was not changed and an attacker was able to gain access to pcsd, they could potentially run shell commands as root. • http://rhn.redhat.com/errata/RHSA-2015-0789.html http://rhn.redhat.com/errata/RHSA-2015-0791.html http://rhn.redhat.com/errata/RHSA-2015-0830.html http://rhn.redhat.com/errata/RHSA-2015-0831.html http://rhn.redhat.com/errata/RHSA-2015-0832.html http://www.securityfocus.com/bid/74049 https://bugzilla.redhat.com/show_bug.cgi?id=1201875 https://access.redhat.com/security/cve/CVE-2015-1842 • CWE-255: Credentials Management Errors CWE-798: Use of Hard-coded Credentials •
CVSS: 2.9EPSS: 0%CPEs: 25EXPL: 0CVE-2014-3615 – Qemu: information leakage when guest sets high resolution
https://notcve.org/view.php?id=CVE-2014-3615
The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution. El emulador VGA en QEMU permite a usuarios locales invitados leer la memoria del anfitrión mediante la configuración de la pantalla a una resolución alta. An information leak flaw was found in the way QEMU's VGA emulator accessed frame buffer memory for high resolution displays. A privileged guest user could use this flaw to leak memory contents of the host to the guest by setting the display to use a high resolution in the guest. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=ab9509cceabef28071e41bdfa073083859c949a7 http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=c1b886c45dc70f247300f549dce9833f3fa2def5 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00014.html http://rhn.redhat.com/errata/RHSA-2014-1669.html http://rhn.redhat.com/errata/RHSA-2014-1670.html http://rhn.redhat.com/errata/RHSA-2014-1941.html http://secunia.com/advisories/61829 http://support.citrix.com/article/CTX200892 http://www.de • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
