https://notcve.org/view.php?id=CVE-2015-1779
The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. El decodificador de frames websocket VNC en QEMU permite a atacantes remotos causar una denegación de servicio (consumo de CPU y memoria) a través de una gran (1) carga útil websocket o (2) sección de cabeceras HTTP It was found that the QEMU's websocket frame decoder processed incoming frames without limiting resources used to process the header and the payload. An attacker able to access a guest's VNC console could use this flaw to trigger a denial of service on the host by exhausting all available memory and CPU. • http://lists.fedoraproject.org/pipermail/package-announce/2015-April/154656.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155196.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00042.html http://rhn.redhat.com/errata/RHSA-2015-1931.html http://rhn.redhat.com/errata/RHSA-2015-1943.html http://www.debian.org/security/2015/dsa-3259 http://www.openwall.com/lists/oss-secu • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

Use-after-free vulnerability in the mozilla::dom::IndexedDB::IDBObjectStore::CreateIndex function in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via crafted content that is improperly handled during IndexedDB index creation. Vulnerabilidad de uso después de liberación en la función mozilla::dom::IndexedDB::IDBObjectStore::CreateIndex en Mozilla Firefox anterior a 36.0, Firefox ESR 31.x anterior a 31.5, y Thunderbird anterior a 31.5 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria dinámica) a través de contenidos manipulados que son manejados incorrectamente durante la creación del índice IndexedDB. • http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-07 • CWE-416: Use After Free •
CVSS: 7.5EPSS: 7%CPEs: 15EXPL: 0CVE-2014-7840 – qemu: insufficient parameter validation during ram load
https://notcve.org/view.php?id=CVE-2014-7840
The host_from_stream_offset function in arch_init.c in QEMU, when loading RAM during migration, allows remote attackers to execute arbitrary code via a crafted (1) offset or (2) length value in savevm data. La función host_from_stream_offset en arch_init.c en QEMU, cuando carga RAM durante la migración, permite a atacantes remotos ejecutar código arbitrario a través de un valor (1) offset o (2) length manipulado en datos savevm. It was found that certain values that were read when loading RAM during migration were not validated. A user able to alter the savevm data (either on the disk or over the wire during migration) could use either of these flaws to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=0be839a2701369f669532ea5884c15bead1c6e08 http://rhn.redhat.com/errata/RHSA-2015-0349.html http://rhn.redhat.com/errata/RHSA-2015-0624.html http://thread.gmane.org/gmane.comp.emulators.qemu/306117 https://bugzilla.redhat.com/show_bug.cgi?id=1163075 https://exchange.xforce.ibmcloud.com/vulnerabilities/99194 https://access.redhat.com/security/cve/CVE-2014-7840 • CWE-20: Improper Input Validation CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2014-8564
The _gnutls_ecc_ansi_x963_export function in gnutls_ecc.c in GnuTLS 3.x before 3.1.28, 3.2.x before 3.2.20, and 3.3.x before 3.3.10 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) Elliptic Curve Cryptography (ECC) certificate or (2) certificate signing requests (CSR), related to generating key IDs. La función _gnutls_ecc_ansi_x963_export en gnutls_ecc.c en GnuTLS 3.x anterior a 3.1.28, 3.2.x anterior a 3.2.20, y 3.3.x anterior a 3.3.10 permite a atacantes remotos causar una denegación de servicio (escritura fuera de rango) a través de un certificado malicioso ECC de tipo (1) curva elíptica criptográfica o (2) peticiones de solicitudes de firma de certificado (CSR), relacionado con la generación de key IDs. An out-of-bounds memory write flaw was found in the way GnuTLS parsed certain ECC (Elliptic Curve Cryptography) certificates or certificate signing requests (CSR). A malicious user could create a specially crafted ECC certificate or a certificate signing request that, when processed by an application compiled against GnuTLS (for example, certtool), could cause that application to crash or execute arbitrary code with the permissions of the user running the application. • http://lists.opensuse.org/opensuse-updates/2014-11/msg00084.html http://rhn.redhat.com/errata/RHSA-2014-1846.html http://secunia.com/advisories/59991 http://secunia.com/advisories/62284 http://secunia.com/advisories/62294 http://www.ubuntu.com/usn/USN-2403-1 https://bugzilla.redhat.com/show_bug.cgi?id=1161443 https://access.redhat.com/security/cve/CVE-2014-8564 • CWE-122: Heap-based Buffer Overflow CWE-310: Cryptographic Issues •
