Stack-based buffer overflow in sys/kern/vfs_mount.c in the kernel in FreeBSD 7.0 and 7.1, when vfs.usermount is enabled, allows local users to gain privileges via a crafted (1) mount or (2) nmount system call, related to copying of "user defined data" in "certain error conditions." Desbordamiento de búfer basado en pila en sys/kern/vfs_mount.c del núcleo de FreeBSD 7.0 y 7.1, cuando vfs.usermount está habilitado; permite a usuarios locales obtener privilegios a través de una llamada al sistema manipulada a (1) mount o (2) nmount. Está relacionado con la copia de "datos definidos por el usuario" en "determinadas condiciones de error". • https://www.exploit-db.com/exploits/9082 http://security.FreeBSD.org/advisories/FreeBSD-SA-08:08.nmount.asc http://www.securityfocus.com/bid/31002 http://www.securitytracker.com/id?1020816 https://exchange.xforce.ibmcloud.com/vulnerabilities/45143 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The kernel in FreeBSD 6.3 through 7.0 on amd64 platforms can make an extra swapgs call after a General Protection Fault (GPF), which allows local users to gain privileges by triggering a GPF during the kernel's return from (1) an interrupt, (2) a trap, or (3) a system call. El kernel de FreeBSD 6.3 hasta 7.0 en las plataformas de amd64 , puede hacer excesivas llamadas swapgs después de un Fallo General de Protección -General Protection Fault (GPF)-; esto permite a usuarios locales obtener privilegios provocando un Fallo General de Protección durante el regreso del kernel desde (1) una interrupción, (2) un paso del proceso de modo de usuario a modo kernel, o (3) una llamada al sistema. • http://secunia.com/advisories/31743 http://security.freebsd.org/advisories/FreeBSD-SA-08:07.amd64.asc http://www.securityfocus.com/bid/31003 http://www.securitytracker.com/id?1020815 https://exchange.xforce.ibmcloud.com/vulnerabilities/44905 • CWE-264: Permissions, Privileges, and Access Controls •

Multiple integer overflows in libc in NetBSD 4.x, FreeBSD 6.x and 7.x, and probably other BSD and Apple Mac OS platforms allow context-dependent attackers to execute arbitrary code via large values of certain integer fields in the format argument to (1) the strfmon function in lib/libc/stdlib/strfmon.c, related to the GET_NUMBER macro; and (2) the printf function, related to left_prec and right_prec. Múltiples desbordamientos de entero en libc de NetBSD 4.x, FreeBSD 6.x y 7.x, y posiblemente otras plataformas BSD y Apple Mac OS permiten a atacantes dependientes del contexto ejecutar código de su elección a través de valores de ciertos campos de enteros en el argumento de formato de (1) la función strfmon en lib/libc/stdlib/strfmon.c, en relación a la macro GET_NUMBER; y (2) la función printf, en relación a left_prec y right_prec. • https://www.exploit-db.com/exploits/31550 http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libc/stdlib/strfmon.c http://lists.apple.com/archives/security-announce//2008//Dec/msg00000.html http://secunia.com/advisories/29574 http://secunia.com/advisories/33179 http://securityreason.com/achievement_securityalert/53 http://securityreason.com/securityalert/3770 http://support.apple.com/kb/HT3338 http://www.debian.org/security/2010/dsa-2058 http://www.securityfocus.com/archive/1/490 • CWE-189: Numeric Errors •

Stack-based buffer overflow in the command_Expand_Interpret function in command.c in ppp (aka user-ppp), as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "~" characters.

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 •
