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 •
