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 •

https://notcve.org/view.php?id=CVE-2015-3195
The ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zh, 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1q, and 1.0.2 before 1.0.2e mishandles errors caused by malformed X509_ATTRIBUTE data, which allows remote attackers to obtain sensitive information from process memory by triggering a decoding failure in a PKCS#7 or CMS application. La implementación ASN1_TFLG_COMBINE en crypto/asn1/tasn_dec.c en OpenSSL en versiones anteriores a 0.9.8zh, 1.0.0 en versiones anteriores a 1.0.0t, 1.0.1 en versiones anteriores a 1.0.1q y 1.0.2 en versiones anteriores a 1.0.2e no maneja correctamente los errores provocados por datos X509_ATTRIBUTE malformados, lo que permite a atacantes remotos obtener información sensible de memoria de proceso desencadenando un fallo de decodificación en una aplicación PKCS#7 o CMS. A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash. • http://fortiguard.com/advisory/openssl-advisory-december-2015 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10733 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/173801.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00009.html http://lists.opensuse& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 7.5EPSS: 2%CPEs: 62EXPL: 0CVE-2015-8126 – libpng: Buffer overflow vulnerabilities in png_get_PLTE/png_set_PLTE functions
https://notcve.org/view.php?id=CVE-2015-8126
Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image. Múltiples desbordamientos de buffer en las funciones (1) png_set_PLTE y (2) png_get_PLTE en libpng en versiones anteriores a 1.0.64, 1.1.x y 1.2.x en versiones anteriores a 1.2.54, 1.3.x y 1.4.x en versiones anteriores a 1.4.17, 1.5.x en versiones anteriores a 1.5.24 y 1.6.x en versiones anteriores a 1.6.19 permiten a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente tener otro impacto no especificado a través de un valor bit-depth pequeño en un fragmento IHDR (también conocido como image header) en una imagen PNG. It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. • http://googlechromereleases.blogspot.com/2016/03/stable-channel-update.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172324.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172620.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172647.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172663.html http://lists.fedoraproject.org/pipermail • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
