CVSS: 6.4EPSS: 1%CPEs: 2EXPL: 1CVE-2016-3115 – OpenSSH 7.2p1 - (Authenticated) xauth Command Injection
https://notcve.org/view.php?id=CVE-2016-3115
Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH before 7.2p2 allow remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions. Múltiples vulnerabilidades de inyección CRLF en session.c en sshd en OpenSSH en versiones anteriores a 7.2p2 permite a usuarios remotos autenticados eludir las restricciones de comandos de shell previstas a través del redireccionamiento de datos X11 manipulados, relacionadas con las funciones (1) do_authenticated1 y (2) session_x11_req. It was discovered that the OpenSSH server did not sanitize data received in requests to enable X11 forwarding. An authenticated client with restricted SSH access could possibly use this flaw to bypass intended restrictions. OpenSSH versions 7.2p1 and below suffer from a command injection and /bin/false bypass vulnerability via xauth. • https://www.exploit-db.com/exploits/39569 http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/session.c http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/session.c.diff?r1=1.281&r2=1.282&f=h http://lists.fedoraproject.org/pipermail/package-announce/2016-April/183101.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/183122.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/178838.html http://lists.fedoraproject.org/pipermail& • CWE-20: Improper Input Validation •
CVSS: 8.8EPSS: 1%CPEs: 33EXPL: 0CVE-2016-1950 – nss: Heap buffer overflow vulnerability in ASN1 certificate parsing (MFSA 2016-35)
https://notcve.org/view.php?id=CVE-2016-1950
Heap-based buffer overflow in Mozilla Network Security Services (NSS) before 3.19.2.3 and 3.20.x and 3.21.x before 3.21.1, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to execute arbitrary code via crafted ASN.1 data in an X.509 certificate. El desbordamiento de buffer basado en memoria dinámica en Mozilla Network Security Services (NSS) en versiones anteriores a 3.19.2.3 y 3.20.x y 3.21.x en versiones anteriores a 3.21.1, tal y como se utiliza en Mozilla Firefox en versiones anteriores a 45.0 y Firefox ESR 38.x en versiones anteriores a 38.7, permiten a atacantes remotos ejecutar código arbitrario a través de datos ASN.1 manipulados en un certificado X.509." A heap-based buffer overflow flaw was found in the way NSS parsed certain ASN.1 structures. An attacker could use this flaw to create a specially crafted certificate which, when parsed by NSS, could cause it to crash, or execute arbitrary code, using the permissions of the user running an application compiled against the NSS library. • http://lists.apple.com/archives/security-announce/2016/Mar/msg00000.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00001.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00002.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2016-03 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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 •

CVSS: 5.1EPSS: 0%CPEs: 30EXPL: 1CVE-2015-2721 – NSS: incorrectly permited skipping of ServerKeyExchange (MFSA 2015-71)
https://notcve.org/view.php?id=CVE-2015-2721
Mozilla Network Security Services (NSS) before 3.19, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, Thunderbird before 38.1, and other products, does not properly determine state transitions for the TLS state machine, which allows man-in-the-middle attackers to defeat cryptographic protection mechanisms by blocking messages, as demonstrated by removing a forward-secrecy property by blocking a ServerKeyExchange message, aka a "SMACK SKIP-TLS" issue. Mozilla Network Security Services (NSS) anterior a 3.19, utilizado en Mozilla Firefox anterior a 39.0, Firefox ESR 31.x anterior a 31.8 y 38.x anterior a 38.1, Thunderbird anterior a 38.1, y otros productos, no determina correctamente las transiciones de estado para la máquina de estados TLS, lo que permite a atacantes man-in-the-middle derrotar los mecanismos de protección criptográfica mediante el bloqueo de mensajes, tal y como fue demostrado mediante la eliminación de una propiedad de confidencialidad adelantada mediante el bloqueo de un mensaje ServerKeyExchange, también conocido como un problema de 'SMACK SKIP-TLS' . It was found that NSS permitted skipping of the ServerKeyExchange packet during a handshake involving ECDHE (Elliptic Curve Diffie-Hellman key Exchange). A remote attacker could use this flaw to bypass the forward-secrecy of a TLS/SSL connection. • http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00021.html http://rhn.redhat.com/errata/RHSA-2015-1185.html http://rhn.redhat.com/errata/RHSA-2015-1664.html http://www.debian.org&#x • CWE-310: Cryptographic Issues CWE-358: Improperly Implemented Security Check for Standard •
