CVE-2013-4854 – ISC BIND rdata Denial Of Service Vulnerability

https://notcve.org/view.php?id=CVE-2013-4854

The RFC 5011 implementation in rdata.c in ISC BIND 9.7.x and 9.8.x before 9.8.5-P2, 9.8.6b1, 9.9.x before 9.9.3-P2, and 9.9.4b1, and DNSco BIND 9.9.3-S1 before 9.9.3-S1-P1 and 9.9.4-S1b1, allows remote attackers to cause a denial of service (assertion failure and named daemon exit) via a query with a malformed RDATA section that is not properly handled during construction of a log message, as exploited in the wild in July 2013. La implementación RFC en rdata.c en ISC BIND 9.7.x y 9.8.x anterior a 9.8.5-P2, 9.8.6b1, 9.9.x anterior a 9.9.3-P2, y 9.9.4b1, y DNSco BIND 9.9.3-S1 anterior a 9.9.3-S1-P1 y 9.9.4-S1b1, permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de una petición con una sección RDATA manipulada que se maneja adecuadamente durante la contrucción de mensaje de log. Ha sido explotada "in the wild" en Julio de 2013. This vulnerability allows remote attackers to cause a denial of service condition on vulnerable installations of ISC BIND. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of an rdata section with a length that is less than four. • http://archives.neohapsis.com/archives/bugtraq/2013-08/0030.html http://archives.neohapsis.com/archives/bugtraq/2014-10/0103.html http://linux.oracle.com/errata/ELSA-2014-1244 http://lists.fedoraproject.org/pipermail/package-announce/2013-August/113108.html http://lists.fedoraproject.org/pipermail/package-announce/2013-August/113251.html http://lists.opensuse.org/opensuse-security-announce/2013-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2013-08/msg00018.html http://rhn. •

CVE-2013-2171 – FreeBSD 9 - Address Space Manipulation Privilege Escalation

https://notcve.org/view.php?id=CVE-2013-2171

The vm_map_lookup function in sys/vm/vm_map.c in the mmap implementation in the kernel in FreeBSD 9.0 through 9.1-RELEASE-p4 does not properly determine whether a task should have write access to a memory location, which allows local users to bypass filesystem write permissions and consequently gain privileges via a crafted application that leverages read permissions, and makes mmap and ptrace system calls. La función vm_map_lookup en sys/vm/vm_map.c en la ejecución de "mmap" en el kernel en FreeBSD v9.0 hasta v9.1-RELEASE-p4 no determina correctamente si una tarea debe tener acceso de escritura a una posición de memoria, que permite a los usuarios locales saltarse permisos de escritura del sistema de archivos y por lo tanto obtener privilegios a través de una aplicación manipulada que aprovecha permisos de lectura, y que hace llamadas al sistema "mmap" y "ptrace". • https://www.exploit-db.com/exploits/26454 https://www.exploit-db.com/exploits/26368 http://svnweb.freebsd.org/base?view=revision&revision=251901 http://www.debian.org/security/2013/dsa-2714 http://www.freebsd.org/security/advisories/FreeBSD-SA-13:06.mmap.asc • CWE-264: Permissions, Privileges, and Access Controls •

CVE-2013-3266

https://notcve.org/view.php?id=CVE-2013-3266

The nfsrvd_readdir function in sys/fs/nfsserver/nfs_nfsdport.c in the new NFS server in FreeBSD 8.0 through 9.1-RELEASE-p3 does not verify that a READDIR request is for a directory node, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code by specifying a plain file instead of a directory. La función nfsrvd_readdir en sys/fs/nfsserver/nfs_nfsdport.c en el nuevo servidor NFS en FreeBSD v8.0 a través de v9.1-RELEASE-p3 no verifica que la solicitud READDIR para un nodo de directorio, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria) o posiblemente ejecutar código arbitrario mediante la especificación de un archivo sin formato en lugar de un directorio. • http://secunia.com/advisories/53241 http://www.debian.org/security/2013/dsa-2672 http://www.freebsd.org/security/advisories/FreeBSD-SA-13:05.nfsserver.asc http://www.securitytracker.com/id/1028491 • CWE-20: Improper Input Validation •

CVE-2013-0211

https://notcve.org/view.php?id=CVE-2013-0211

Integer signedness error in the archive_write_zip_data function in archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running on 64-bit machines, allows context-dependent attackers to cause a denial of service (crash) via unspecified vectors, which triggers an improper conversion between unsigned and signed types, leading to a buffer overflow. Error de signo de enteros en la función archive_write_zip_data de archive_write_set_format_zip.c en la versión 3.1.2 y anteriores, cuando se ejecuta en equipos de 64 bits, permite a atacantes dependientes del contexto causar una denegación del servicio (caída) a través de vectores sin especificar, que desencadena en una conversión incorrecta entre tipos con signo y sin signo, dando lugar a un desbordamiento de búfer. • http://lists.fedoraproject.org/pipermail/package-announce/2013-April/101687.html http://lists.fedoraproject.org/pipermail/package-announce/2013-April/101700.html http://lists.fedoraproject.org/pipermail/package-announce/2013-April/101872.html http://lists.fedoraproject.org/pipermail/package-announce/2013-April/101876.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00065.html http://www.mandriva.com/security/advisories?name=MDVSA-2013:147 http://www.securityfocus.com/bid/58926 http://www.securi • CWE-189: Numeric Errors •
