CVE-2013-4312 – kernel: File descriptors passed over unix sockets are not properly accounted
https://notcve.org/view.php?id=CVE-2013-4312
The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c. El kernel de Linux en versiones anteriores a 4.4.1 permite a usuarios locales eludir los limites de descriptor de fichero y provocar una denegación de servicio (consumo de memoria) enviando cada descriptor a través de un socket UNIX antes de cerrarlo, relacionado con net/unix/af_unix.c y net/unix/garbage.c. It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=712f4aad406bb1ed67f3f98d04c044191f0ff593 http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176464.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176484.html http://rhn.redhat.com/errata/RHSA-2016-0855.html http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2016/dsa-3448 http://www.debian.or • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-400: Uncontrolled Resource Consumption •
CVE-2016-0777 – OpenSSH: Client Information leak due to use of roaming connection feature
https://notcve.org/view.php?id=CVE-2016-0777
The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key. La función resend_bytes en roaming_common.c en el cliente en OpenSSH 5.x, 6.x y 7.x en versiones anteriores a 7.1p2 permite a servidores remotos obtener información sensible desde la memoria de proceso mediante la petición de transmisión de un buffer completo, según lo demostrado mediante la lectura de una clave privada. An information leak flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to leak portions of memory (possibly including private SSH keys) of a successfully authenticated OpenSSH client. • 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/175592.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/175676.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176349.html http://lists.opensuse.org/opensuse-security-announce • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-682: Incorrect Calculation •
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-2015-7512 – 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 •
