CVE-2008-1147
https://notcve.org/view.php?id=CVE-2008-1147
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 •
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-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/ •
