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-2009-0687 – Multiple Vendor - PF Null Pointer Dereference
https://notcve.org/view.php?id=CVE-2009-0687
The pf_test_rule function in OpenBSD Packet Filter (PF), as used in OpenBSD 4.2 through 4.5, NetBSD 5.0 before RC3, MirOS 10 and earlier, and MidnightBSD 0.3-current allows remote attackers to cause a denial of service (panic) via crafted IP packets that trigger a NULL pointer dereference during translation, related to an IPv4 packet with an ICMPv6 payload. La función pf_test_rule de OpenBSD Packet Filter (PF), tal como es usada en OpenBSD v4.2 hasta v4.5, NetBSD v5.0 anterior a RC3, MirOS v10 y anteriores y MidnightBSD v0.3 hasta la versión actual permite a atacantes remotos causar una denegación de servicio a través de paquetes IP modificados que provocan una "desreferencia" de un puntero nulo relacionada con un paquete IPv4 con datos ("payload") ICMPv6. • https://www.exploit-db.com/exploits/8581 https://www.exploit-db.com/exploits/8430 https://www.exploit-db.com/exploits/8406 ftp://ftp.openbsd.org/pub/OpenBSD/patches/4.3/common/013_pf.patch http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2009-001.txt.asc http://www.helith.net/txt/multiple_vendor-PF_null_pointer_dereference.txt http://www.openbsd.org/errata43.html#013_pf http://www.openbsd.org/errata44.html#013_pf http://www.openbsd.org/errata45.html • CWE-399: Resource Management Errors •
CVE-2009-0537 – Libc - 'libc:fts_*()' Local Denial of Service
https://notcve.org/view.php?id=CVE-2009-0537
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 •
