https://notcve.org/view.php?id=CVE-2016-1568
Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command. Vulnerabilidad de uso después de liberación de memoria en hw/ide/ahci.c en QEMU, cuando se construye con soporte de emulación IDE AHCI, permite a usuarios del SO invitado causar una denegación de servicio (caída de instancia) o posiblemente ejecutar código arbitrario a través de un comando AHCI Native Command Queuing (NCQ) AIO no válido. A use-after-free flaw was found in the way QEMU's IDE AHCI emulator processed certain AHCI Native Command Queuing (NCQ) AIO commands. A privileged guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=4ab0359a8ae182a7ac5c99609667273167703fab http://rhn.redhat.com/errata/RHSA-2016-0084.html http://rhn.redhat.com/errata/RHSA-2016-0086.html http://rhn.redhat.com/errata/RHSA-2016-0087.html http://rhn.redhat.com/errata/RHSA-2016-0088.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/2016/0 • CWE-416: Use After Free •
CVSS: 7.1EPSS: 0%CPEs: 17EXPL: 0CVE-2015-5312 – libxml2: CPU exhaustion when processing specially crafted XML input
https://notcve.org/view.php?id=CVE-2015-5312
The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660. La función xmlStringLenDecodeEntities en parser.c en libxml2 en versiones anteriores a 2.9.3 no previene adecuadamente la expansión de entidad, lo que permite a atacantes dependientes del contexto causar una denegación de servicio (consumo de CPU) a través de datos XML manipulados, una vulnerabilidad diferente a CVE-2014-3660. 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 use an excessive amount of CPU. • http://lists.apple.com/archives/security-announce/2016/Mar/msg00000.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00001.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00002.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html 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 • CWE-399: Resource Management Errors •

The xmlParseMisc function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (out-of-bounds heap read) via unspecified vectors related to incorrect entities boundaries and start tags. La función xmlParseMisc en parser.c en libxml2 en versiones anteriores a 2.9.3 permite a atacantes dependientes del contexto causar una denegación de servicio (lectura de memoria dinámica fuera de rango) a través de vectores no especificados relacionados con límites de entidades y etiquetas de inicio incorrectos.
