CVE-2017-3137 – A response packet can cause a resolver to terminate when processing an answer containing a CNAME or DNAME
https://notcve.org/view.php?id=CVE-2017-3137
Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order. Affects BIND 9.9.9-P6, 9.9.10b1->9.9.10rc1, 9.10.4-P6, 9.10.5b1->9.10.5rc1, 9.11.0-P3, 9.11.1b1->9.11.1rc1, and 9.9.9-S8. Las asunciones equivocadas sobre el orden de los registros en la sección de respuesta de una respuesta que contiene registros de recursos CNAME o DNAME podría conducir a una situación en la que named se cerraría con un fallo de aserción al procesar una respuesta en la que los registros ocurrieron en un orden inusual. Afecta a BIND en versiones 9.9.9-P6, desde la versión 9.9.10b1 hasta la 9.9.10rc1, la versión 9.10.4-P6, desde la versión 9.10.5b1 hasta la 9.10.5rc1, la versión 9.11.0-P3, desde la versión 9.11.1b1 hasta la 9.11.1rc1 y en la versión 9.9.9-S8. A denial of service flaw was found in the way BIND handled a query response containing CNAME or DNAME resource records in an unusual order. • http://www.securityfocus.com/bid/97651 http://www.securitytracker.com/id/1038258 http://www.securitytracker.com/id/1040195 https://access.redhat.com/errata/RHSA-2017:1095 https://access.redhat.com/errata/RHSA-2017:1105 https://access.redhat.com/errata/RHSA-2017:1582 https://access.redhat.com/errata/RHSA-2017:1583 https://kb.isc.org/docs/aa-01466 https://security.gentoo.org/glsa/201708-01 https://security.netapp.com/advisory/ntap-20180802-0002 https://www.debian.org& • CWE-617: Reachable Assertion •
CVE-2016-8864 – bind: assertion failure while handling responses containing a DNAME answer
https://notcve.org/view.php?id=CVE-2016-8864
named in ISC BIND 9.x before 9.9.9-P4, 9.10.x before 9.10.4-P4, and 9.11.x before 9.11.0-P1 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a DNAME record in the answer section of a response to a recursive query, related to db.c and resolver.c. named en ISC BIND 9.x en versiones anteriores a 9.9.9-P4, 9.10.x en versiones anteriores a 9.10.4-P4 y 9.11.x en versiones anteriores a 9.11.0-P1 permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de un registro DNAME en la sección de respuesta de una respuesta a una petición recursiva, relacionado con db.c y resolver.c. A denial of service flaw was found in the way BIND handled responses containing a DNAME answer. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. • http://rhn.redhat.com/errata/RHSA-2016-2141.html http://rhn.redhat.com/errata/RHSA-2016-2142.html http://rhn.redhat.com/errata/RHSA-2016-2615.html http://rhn.redhat.com/errata/RHSA-2016-2871.html http://www.debian.org/security/2016/dsa-3703 http://www.securityfocus.com/bid/94067 http://www.securitytracker.com/id/1037156 https://access.redhat.com/errata/RHSA-2017:1583 https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05381687 https: • CWE-617: Reachable Assertion •
CVE-2014-7169 – GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •

CVE-2014-5077 – Kernel: net: SCTP: fix a NULL pointer dereference during INIT collisions
https://notcve.org/view.php?id=CVE-2014-5077
The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction. La función sctp_assoc_update en net/sctp/associola.c en el kernel de Linux hasta 3.15.8, cuando la autenticación SCTP está habilitada, permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y OOPS) mediante el inicio del establecimiento de una asociación entre dos endpoints inmediatamente después de un intercambio de fragmentos INIT y INIT ACK para establecer una asociación anterior entre estos endpoints en la dirección opuesta. A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1be9a950c646c9092fb3618197f7b6bfb50e82aa http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://rhn.redhat.com/errata/RHSA-2014-1083.html http://rhn.redhat.com/errata/RHSA-2014-1668.html http://rhn.redhat.com/errata/RHSA-2014-1763.html http://secunia.com/advisories/59777 http://secunia.com/advisories/60430 h • CWE-476: NULL Pointer Dereference •
