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.

A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting. Cierto algoritmo generador de números pseudo-aleatorios(PRNG) que usa XOR y alterna en saltos de 2-bit (también conocido com o"algoritmo X2"), usado en OpenBSD de la v2.6 a la 3.4, Mac OS X de la v10 a a 10.5.1, FreeBSD 4.4 a la 7.0 y DragonFlyBSD 1.0 a la 1.10.1, permite a atacantes remotos adivinar datos sensibles como los IDs de una fragmentación IP observando una secuencia generada previamente. NOTA: este fallo puede ser aprovechado por ataques como la inyección de paquetes TCP y OS fingerprinting. • http://seclists.org/bugtraq/2008/Feb/0052.html http://seclists.org/bugtraq/2008/Feb/0063.html http://secunia.com/advisories/28819 http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet/ip_id.c?rev=1.10%3Bcontenttype= 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://e •
