CVE-2008-1146
https://notcve.org/view.php?id=CVE-2008-1146
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. NOTA: esta cuestión puede ser aprovechado por ataques como el envenenamiento de la caché DNS contra la modificación BIND en OpenBDS. • 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 •
CVE-2008-1148
https://notcve.org/view.php?id=CVE-2008-1148
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 •
CVE-2007-5365 – Ubuntu 6.06 - DHCPd Remote Denial of Service
https://notcve.org/view.php?id=CVE-2007-5365
Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU. Un desbordamiento de búfer en la región stack de la memoria en la función cons_options en el archivo options.c en dhcpd en OpenBSD versiones 4.0 hasta 4.2, y algunas otras implementaciones de dhcpd basadas en ISC dhcp-2, permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (bloqueo del demonio) por medio de una petición DHCP que especifica un tamaño máximo de mensaje más pequeño que el IP MTU mínimo. • https://www.exploit-db.com/exploits/4601 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=446354 http://secunia.com/advisories/27160 http://secunia.com/advisories/27273 http://secunia.com/advisories/27338 http://secunia.com/advisories/27350 http://secunia.com/advisories/32668 http://securitytracker.com/id?1021157 http://sunsolve.sun.com/search/document.do?assetkey=1-21-109077-21-1 http://sunsolve.sun.com/search/document.do?assetkey=1-26-243806-1 http://www.coresecurity • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2007-1352 – Multiple font integer overflows (CVE-2007-1352)
https://notcve.org/view.php?id=CVE-2007-1352
Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow. Desbordamiento de entero en la función FontFileInitTable en X.Org libXfont versiones anteriores a 20070403 permite a usuarios remotos autenticados ejecutar código de su elección mediante una primera línea larga en el fichero fonts.dir, lo cual resulta en un desbordamiento de montón. • http://issues.foresightlinux.org/browse/FL-223 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=502 http://lists.apple.com/archives/Security-announce/2007/Nov/msg00003.html http://lists.apple.com/archives/security-announce/2009/Feb/msg00000.html http://lists.freedesktop.org/archives/xorg-announce/2007-April/000286.html http://rhn.redhat.com/errata/RHSA-2007-0125.html http://secunia.com/advisories/24741 http://secunia.com/advisories/24745 http://secunia.com/advisories/ •
