CVE-2016-0778 – OpenSSH: Client buffer-overflow when using roaming connections
https://notcve.org/view.php?id=CVE-2016-0778
The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings. Las funciones (1) roaming_read y (2) roaming_write en roaming_common.c en el cliente en OpenSSH 5.x, 6.x y 7.x en versiones anteriores a 7.1p2, cuando ciertas opciones proxy y forward se encuentran habilitadas, no mantiene adecuadamente los descriptores de archivo de conexión, lo que permite a servidores remotos causar una denegación de servicio (desbordamiento de buffer basado en memoria dinámica) o posiblemente tener otro impacto no especificado mediante la petición de varios reenvíos. A buffer overflow flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to execute arbitrary code on a successfully authenticated OpenSSH client if that client used certain non-default configuration options. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10734 http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176516.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176349.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-01& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

CVE-2015-8000 – bind: responses with a malformed class attribute can trigger an assertion failure in db.c
https://notcve.org/view.php?id=CVE-2015-8000
db.c in named in ISC BIND 9.x before 9.9.8-P2 and 9.10.x before 9.10.3-P2 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via a malformed class attribute. db.c en named en ISC BIND 9.x en versiones anteriores a 9.9.8-P2 y 9.10.x en versiones anteriores a 9.10.3-P2 permite a atacantes remotos causar una denegación de servicio (falla de aserción REQUIRE y salida del demonio) a través de un atributo de clase mal formado. A denial of service flaw was found in the way BIND processed certain records with malformed class attributes. A remote attacker could use this flaw to send a query to request a cached record with a malformed class attribute that would cause named functioning as an authoritative or recursive server to crash. Note: This issue affects authoritative servers as well as recursive servers, however authoritative servers are at limited risk if they perform authentication when making recursive queries to resolve addresses for servers listed in NS RRSETs. • http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174143.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174145.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174252.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174520.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00028.html http://lists.opensuse.org/opensuse-se • CWE-20: Improper Input Validation •
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 •
CVE-2015-8104 – virt: guest to host DoS by triggering an infinite loop in microcode via #DB exception
https://notcve.org/view.php?id=CVE-2015-8104
The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c. El subsistema KVM en el kernel Linux hasta la versión 4.2.6, y Xen 4.3.x hasta la versión 4.6.x permite a usuarios del SO invitados causar una denegación de servicio (panic en el host del SO o cuelgue) desencadenando muchas excepciones #DB (también conocidas como Debug), relacionadas con svm.c. It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #DB (debug exception) is handled. A privileged user inside a guest could use this flaw to create denial of service conditions on the host kernel. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cbdb967af3d54993f5814f1cee0ed311a055377d http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172187.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172300.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172435.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00005.html http:/ • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
