CVE-2016-2857 – Qemu: net: out of bounds read in net_checksum_calculate()
https://notcve.org/view.php?id=CVE-2016-2857
The net_checksum_calculate function in net/checksum.c in QEMU allows local guest OS users to cause a denial of service (out-of-bounds heap read and crash) via the payload length in a crafted packet. La función net_checksum_calculate en net/checksum.c en QEMU permite a usuarios del SO invitado provocar una denegación de servicio (lectura de memoria dinámica fuera de rango y caída) a través de una longitud de la carga útil en un paquete manipulado. An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). • http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=362786f14a753d8a5256ef97d7c10ed576d6572b http://rhn.redhat.com/errata/RHSA-2016-2670.html http://rhn.redhat.com/errata/RHSA-2016-2671.html http://rhn.redhat.com/errata/RHSA-2016-2704.html http://rhn.redhat.com/errata/RHSA-2016-2705.html http://rhn.redhat.com/errata/RHSA-2016-2706.html http://rhn.redhat.com/errata/RHSA-2017-0083.html http://rhn.redhat.com/errata/RHSA-2017-0309.html http://rhn.redhat.com/errata/RHSA- • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVE-2015-8540 – libpng: underflow read in png_check_keyword()
https://notcve.org/view.php?id=CVE-2015-8540
Integer underflow in the png_check_keyword function in pngwutil.c in libpng 0.90 through 0.99, 1.0.x before 1.0.66, 1.1.x and 1.2.x before 1.2.56, 1.3.x and 1.4.x before 1.4.19, and 1.5.x before 1.5.26 allows remote attackers to have unspecified impact via a space character as a keyword in a PNG image, which triggers an out-of-bounds read. Desbordamiento inferior de entero en la función png_check_keyword en pngwutil.c en libpng 0.90 hasta la versión 0.99, 1.0.x en versiones anteriores a 1.0.66, 1.1.x y 1.2.x en versiones anteriores a 1.2.56, 1.3.x y 1.4.x en versiones anteriores a 1.4.19 y 1.5.x en versiones anteriores a 1.5.26 permite a atacantes remotos tener un impacto no especificado a través de un carácter de espacio como contraseña en una imagen PNG, lo que desencadena una lectura fuera de rango. • http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174435.html http://sourceforge.net/p/libpng/bugs/244 http://sourceforge.net/p/libpng/code/ci/d9006f683c641793252d92254a75ae9b815b42ed http://sourceforge.net/projects/libpng/files/libpng10/1.0.66 http://sourceforge.net/projects/libpng/files/libpng12/1.2.56 http://sourceforge.net/projects/libpng/files/libpng14/1.4.19 http://sourceforge.net/projects/libpng/files/libpng15/1.5.26 http://www.debian.org/security/2016/dsa-34 • CWE-125: Out-of-bounds Read CWE-189: Numeric Errors •
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-2015-3195 – OpenSSL: X509_ATTRIBUTE memory leak
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 •
