CVE-2015-7498 – libxml2: Heap-based buffer overflow in xmlParseXmlDecl
https://notcve.org/view.php?id=CVE-2015-7498
Heap-based buffer overflow in the xmlParseXmlDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service via unspecified vectors related to extracting errors after an encoding conversion failure. Desbordamiento de buffer basado en memoria dinámica en la función xmlParseXmlDecl en parser.c en libxml2 en versiones anteriores a 2.9.3 permite a atacantes dependientes del contexto causar una denegación de servicio a través de vectores no especificados relacionados con errores de extracción después de un fallo de conversión de la codificación. A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to crash. • http://lists.opensuse.org/opensuse-updates/2015-12/msg00120.html http://lists.opensuse.org/opensuse-updates/2016-01/msg00031.html http://marc.info/?l=bugtraq&m=145382616617563&w=2 http://rhn.redhat.com/errata/RHSA-2015-2549.html http://rhn.redhat.com/errata/RHSA-2015-2550.html http://rhn.redhat.com/errata/RHSA-2016-1089.html http://www.debian.org/security/2015/dsa-3430 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

CVE-2015-7512 – Qemu: net: pcnet: buffer overflow in non-loopback mode
https://notcve.org/view.php?id=CVE-2015-7512
Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet. Desbordamiento de buffer en la función pcnet_receive en hw/net/pcnet.c en QEMU, cuando un NIC invitado tiene un MTU más grande, permite a atacantes provocar una denegación de servicio (caída de SO invitado) o ejecutar código arbitrario a través de un paquete grande. A buffer overflow flaw was found in the way QEMU's AMD PC-Net II emulation validated certain received packets from a remote host in non-loopback mode. A remote, unprivileged attacker could potentially use this flaw to execute arbitrary code on the host with the privileges of the QEMU process. Note that to exploit this flaw, the guest network interface must have a large MTU limit. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=8b98a2f07175d46c3f7217639bd5e03f http://rhn.redhat.com/errata/RHSA-2015-2694.html http://rhn.redhat.com/errata/RHSA-2015-2695.html http://rhn.redhat.com/errata/RHSA-2015-2696.html http://www.debian.org/security/2016/dsa-3469 http://www.debian.org/security/2016/dsa-3470 http://www.debian.org/security/2016/dsa-3471 http://www.openwall.com/lists/oss-security/2015/11/30/3 http://www.oracle.com/technetwork/topics/securi • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-122: Heap-based Buffer Overflow •
CVE-2015-5165 – Qemu: rtl8139 uninitialized heap memory information leakage to guest (XSA-140)
https://notcve.org/view.php?id=CVE-2015-5165
The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. Vulnerabilidad en la emulación de modo offload C+ en el modelo de tarjeta de red del dispositivo RTL8139 en QEMU, tal y como se utiliza en Xen 4.5.x y versiones anteriores, permite a atacantes remotos leer la memoria dinámica del proceso a través de vectores no especificados. An information leak flaw was found in the way QEMU's RTL8139 emulation implementation processed network packets under RTL8139 controller's C+ mode of operation. An unprivileged guest user could use this flaw to read up to 65 KB of uninitialized QEMU heap memory. • http://lists.fedoraproject.org/pipermail/package-announce/2015-September/165373.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/167792.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/167820.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00027.html http://rhn.redhat.com/errata/RHSA-2015-1674.html http://rhn.redhat.com/errata/RHSA-2015-1683.html http: • CWE-456: Missing Initialization of a Variable CWE-908: Use of Uninitialized Resource •
CVE-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 •
