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 •

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.

A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND. Cierto algoritmo generador de números pseudo-aleatorios(PRNG) que usa XOR y alterna en saltos de 3-bit (también conocido com o"algoritmo X3"), usado en OpenBSD de la v2.8 a la 4.2, permite a atacantes remotos adivinar datos sensibles como los IDs de una transacción DNS, observando una secuencia de datos generada previamente.

Integer signedness error in the fw_ioctl (FW_IOCTL) function in the FireWire (IEEE-1394) drivers (dev/firewire/fwdev.c) in various BSD kernels, including DragonFlyBSD, FreeBSD 5.5, MidnightBSD 0.1-CURRENT before 20061115, NetBSD-current before 20061116, NetBSD-4 before 20061203, and TrustedBSD, allows local users to read arbitrary memory contents via certain negative values of crom_buf->len in an FW_GCROM command. NOTE: this issue has been labeled as an integer overflow, but it is more like an integer signedness error. Error de presencia de signo en entero en la función fw_ioctl (FW_IOCTL) en los controladores (dev/firewire/fwdev.c) FireWire (IEEE-1394) en varios núcleos de BSD, incluyendo DragonFlyBSD, FreeBSD 5.5, MidnightBSD 0.1-CURRENT anterior al 15/11/2006, NetBSD-current anterior al 16/11/2006, NetBSD-4 anterior al 03/12/2006, y TrustedBSD, permite a usuarios locales leer contenidos de la memoria de su elección mediante ciertos valores negativos de crom_buf->len en un comando FW_GCROM. Nota: este asunto ha sido etiquetado como un desbordamiento de entero, pero se parece más a un error de presencia de signo en entero. • http://archives.neohapsis.com/archives/fulldisclosure/2006-11/0261.html http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/ieee1394/fwdev.c http://mail-index.netbsd.org/tech-security/2006/11/16/0001.html http://mail-index.netbsd.org/tech-security/2006/12/14/0002.html http://secunia.com/advisories/22917 http://security.freebsd.org/advisories/FreeBSD-SA-06:25.kmem.asc http://securitytracker.com/id?1017344 http://www.dragonflybsd.org/cvsweb/src/sys/bus/firewire/fwdev.c http: •
