The (1) remote_glob function in sftp-glob.c and the (2) process_put function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in SSH_FXP_STAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632. La (1) función remote_glob en sftp-glob.c y (2) la función process_put en sftp.c en OpenSSH v5.8 y versiones anteriores, como se usa en FreeBSD v7.3 y v8.1, NetBSD v5.0.2, OpenBSD v4.7 y otros productos, permiten a usuarios remotos autenticados causar una denegación de servicio (por excesivo uso de CPU y consumo de memoria) a través de expresiones glob debidamente modificadas que no coinciden con ningún nombre de ruta, como lo demuestran las expresiones glob en las solicitudes SSH_FXP_STAT a un demonio de sftp. Se trata de una vulnerabilidad diferente a CVE-2010-2632. • http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/crypto/dist/ssh/Attic/sftp-glob.c#rev1.13.12.1 http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/crypto/dist/ssh/Attic/sftp.c#rev1.21.6.1 http://cxib.net/stuff/glob-0day.c http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2010-008.txt.asc http://securityreason.com/achievement_securityalert/89 http://securityreason.com/exploitalert/9223 http://securityreason.com/securityalert/8116 • CWE-399: Resource Management Errors •

Integer overflow in the fts_build function in fts.c in libc in (1) OpenBSD 4.4 and earlier and (2) Microsoft Interix 6.0 build 10.0.6030.0 allows context-dependent attackers to cause a denial of service (application crash) via a deep directory tree, related to the fts_level structure member, as demonstrated by (a) du, (b) rm, (c) chmod, and (d) chgrp on OpenBSD; and (e) SearchIndexer.exe on Vista Enterprise. Desbordamiento de entero en la función fts_build en fts.c de libc sobre (1) OpenBSD v4.4 y anteriores y (2) Microsoft Interix v6.0 build 10.0.6030.0, permiten a atacantes, dependiendo del contexto, provocar una denegación de servicio (caída de la aplicación) a través de un arbol de directorio profundo, relativo al miembro de la estructura fts_level, como se ha demostrado por (a) du, (b) rm, (c) chmod, y (d) chgrp en OpenBSD; y (e)SearchIndexer.exe en Vista Enterprise. • https://www.exploit-db.com/exploits/8163 http://securityreason.com/achievement_securityalert/60 http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/fts.c http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/fts.c.diff?r1=1.41%3Br2=1.42%3Bf=h http://www.securityfocus.com/archive/1/501505/100/0/threaded http://www.securityfocus.com/bid/34008 http://www.securitytracker.com/id?1021818 • CWE-189: Numeric Errors •

The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress. La implementación del protocolo TCP en (1) Linux, (2) plataformas basadas en BSD Unix, (3) Microsoft Windows, (4) productos Cisco, y probablemente otros sistemas operativos, permite a atacantes remotos provocar una denegación de servicio (agotamiento de cola de conexión) a través de múltiples vectores que manipulan información en la tabla de estados del TCP, como lo demuestra sockstress. • http://blog.robertlee.name/2008/10/conjecture-speculation.html http://insecure.org/stf/tcp-dos-attack-explained.html http://lists.immunitysec.com/pipermail/dailydave/2008-October/005360.html http://marc.info/?l=bugtraq&m=125856010926699&w=2 http://searchsecurity.techtarget.com.au/articles/27154-TCP-is-fundamentally-borked http://www.cisco.com/en/US/products/products_security_advisory09186a0080af511d.shtml http://www.cisco.com/en/US/products/products_security_response09186a0080a15120.html http://www.cpni • CWE-16: Configuration •

A certain pseudo-random number generator (PRNG) algorithm that uses ADD with 0 random hops (aka "Algorithm A0"), as used in OpenBSD 3.5 through 4.2 and NetBSD 1.6.2 through 4.0, allows remote attackers to guess sensitive values such as (1) DNS transaction IDs or (2) IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning, injection into TCP packets, and OS fingerprinting. Cierto algoritmo generador de números pseudo-aleatorios(PRNG) que usa ADD con 0 saltos aleatorios(también conocido como "algoritmo A0"), usado en OpenBSD de la v3.5 a la 4.2 y NetBSD v1.6.2 a la 4.0, permite a atacantes remotos adivinar datos sensibles como (1)los IDs de una transacción DNS, (2)IDs de una fragmentación IP observando una secuencias generadas previamente. NOTA: este fallo puede ser aprovechado por ataques como el envenenamiento de la cachés DNS, la inyección de paquetes TCP y OS fingerprinting. • http://secunia.com/advisories/28819 http://www.securiteam.com/securityreviews/5PP0H0UNGW.html http://www.securityfocus.com/archive/1/487658 http://www.securityfocus.com/bid/27647 http://www.trusteer.com/docs/OpenBSD_DNS_Cache_Poisoning_and_Multiple_OS_Predictable_IP_ID_Vulnerability.pdf https://exchange.xforce.ibmcloud.com/vulnerabilities/40329 https://exchange.xforce.ibmcloud.com/vulnerabilities/41157 •
