CVE-2011-0419 – Apache 1.4/2.2.x - APR 'apr_fnmatch()' Denial of Service
https://notcve.org/view.php?id=CVE-2011-0419
Stack consumption vulnerability in the fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library before 1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle Solaris 10, and Android, allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via *? sequences in the first argument, as demonstrated by attacks against mod_autoindex in httpd. Vulnerabilidad de agotamiento de pila en la función fnmatch implementada en apr_fnmatch.c en la librería de Apache Portable Runtime (APR) anterior a v1.4.3 y en Apache HTTP Server anterior a v2.2.18, y en fnmatch.c en libc en NetBSD v5.1, OpenBSD v4.8, FreeBSD, Apple Mac OS X v10.6, Oracle Solaris 10, y Android permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de CPU y memoria) a través de secuencias "*?" en el primer argumento, como se demostró con los ataques contra mod_autoindex en httpd. • https://www.exploit-db.com/exploits/35738 http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libc/gen/fnmatch.c#rev1.22 http://cxib.net/stuff/apache.fnmatch.phps http://cxib.net/stuff/apr_fnmatch.txts http://httpd.apache.org/security/vulnerabilities_22.html http://lists.apple.com/archives/Security-announce/2011//Oct/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-11/msg00011.html http://marc.info/?l=bugtraq&m=131551295528105&w=2 http://marc.info/ • CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2011-1013 – kernel: drm_modeset_ctl signedness issue
https://notcve.org/view.php?id=CVE-2011-1013
Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument. Error de enteros sin signo en Función drm_modeset_ctl en(1) drivers /gpu/drm/drm_irq.c del subsistema Direct Rendering Manager del kernel de Linux con anterioridad a v2.6.38 y (2) sys/dev/pci/drm/drm_irq.c en el kernel de OpenBSD con anterioridad a v4.9 permite a los usuarios locales provocar una salida de los limites en las operaciones de escritura, y por lo tanto provocar una denegación de servicio ( caída del sistema ) o, posiblemente,tener un impacto no especificado, a través de un miembro de la estructura num_crtcs ( vb_num alias ) manipulado en un argumento ioctl. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1922756124ddd53846877416d92ba4a802bc658f http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.38 http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/drm/drm_irq.c http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/drm/drm_irq.c.diff?r1=1.41%3Br2=1.42%3Bf=h http://www.securityfocus.com/bid/47639 https://bugzilla.redhat.com/show_bug.cgi?id=679925 https://exchange. • CWE-787: Out-of-bounds Write •
CVE-2010-4755
https://notcve.org/view.php?id=CVE-2010-4755
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 •
CVE-2008-4609
https://notcve.org/view.php?id=CVE-2008-4609
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.

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 •
