The replay functionality for ZFS Intent Log (ZIL) in FreeBSD 7.1, 7.2, and 8.0, when creating files during replay of a setattr transaction, uses 7777 permissions instead of the original permissions, which might allow local users to read or modify unauthorized files in opportunistic circumstances after a system crash or power failure. La funcionalidad replay para ZFS Intent Log (ZIL) en FreeBSD versiones 7.1, 7.2 y 8.0, al crear archivos durante la reproducción de una transacción setattr, utiliza 7777 permisos en lugar de los permisos originales, lo que podría permitir a los usuarios locales leer o modificar archivos no autorizados en circunstancias oportunistas luego de un fallo del sistema o fallo eléctrico. • http://secunia.com/advisories/38124 http://security.FreeBSD.org/advisories/FreeBSD-SA-10:03.zfs.asc http://www.securityfocus.com/bid/37657 http://www.securitytracker.com/id?1023407 • CWE-264: Permissions, Privileges, and Access Controls •

freebsd-update in FreeBSD 8.0, 7.2, 7.1, 6.4, and 6.3 uses insecure permissions in its working directory (/var/db/freebsd-update by default), which allows local users to read copies of sensitive files after a (1) freebsd-update fetch (fetch) or (2) freebsd-update upgrade (upgrade) operation. FreeBSD-update en FreeBSD v8.0, v7.2, v7.1, v6.4, y v6.3 utiliza permisos inseguros en su directorio de trabajo (/var/db/Freebsd-update por defecto), lo que permite leer las copias de archivos confidenciales a usuarios locales después de una operacion de actualización (1) freebsd-update (fetch) o (2) freebsd-update (upgrade). • http://secunia.com/advisories/37575 http://security.freebsd.org/advisories/FreeBSD-SA-09:17.freebsd-update.asc http://www.securityfocus.com/bid/37190 • CWE-264: Permissions, Privileges, and Access Controls •

The _rtld function in the Run-Time Link-Editor (rtld) in libexec/rtld-elf/rtld.c in FreeBSD 7.1 and 8.0 does not clear the (1) LD_LIBMAP, (2) LD_LIBRARY_PATH, (3) LD_LIBMAP_DISABLE, (4) LD_DEBUG, and (5) LD_ELF_HINTS_PATH environment variables, which allows local users to gain privileges by executing a setuid or setguid program with a modified variable containing an untrusted search path that points to a Trojan horse library, different vectors than CVE-2009-4146. La función _rtld en Run-Time Link-Editor (rtld) en libexec/rtld-elf/rtld.c en FreeBSD v7.1 y v8.0 no limpia las variables de entorno de (1) LD_LIBMAP, (2) LD_LIBRARY_PATH, (3) LD_LIBMAP_DISABLE, (4) LD_DEBUG, and (5) LD_ELF_HINTS_PATH lo que permite a usuarios locales conseguir privilegios mediante la ejecución de un programa setuid o setguid con una variable modificada que contiene una ruta de búsqueda sin confianza que apunta a una libreria de un troyano con vectores diferentes que CVE-2009-4146. • https://www.exploit-db.com/exploits/10255 http://packetstormsecurity.com/files/152997/FreeBSD-rtld-execl-Privilege-Escalation.html http://people.freebsd.org/~cperciva/rtld.patch http://secunia.com/advisories/37517 http://www.securityfocus.com/archive/1/508142/100/0/threaded http://www.securityfocus.com/archive/1/508146/100/0/threaded http://www.securityfocus.com/bid/37154 http://www.securitytracker.com/id?1023250 https://seclists.org/fulldisclosure/2009/Nov/371 https://c-skills& • CWE-264: Permissions, Privileges, and Access Controls •

The _rtld function in the Run-Time Link-Editor (rtld) in libexec/rtld-elf/rtld.c in FreeBSD 7.1, 7.2, and 8.0 does not clear the LD_PRELOAD environment variable, which allows local users to gain privileges by executing a setuid or setguid program with a modified LD_PRELOAD variable containing an untrusted search path that points to a Trojan horse library, a different vector than CVE-2009-4147. La función _rtld en el Run-Time Link-Editor (rtld) de libexec/rtld-elf/rtld.c de FreeBSD v7.1, v7.2 y v8.0, no limpia la variable de entorno LD_PRELOAD, esto permite a usuarios locales aumentar sus privilegios al ejecutar el programa setuid o setguid con la variable LD_PRELOAD modificada para que contenga una ruta de búsqueda no confiable que apunte a una biblioteca de un Troyano.

Opera before 10.00 on Linux, Solaris, and FreeBSD does not properly implement the "INPUT TYPE=file" functionality, which allows remote attackers to trick a user into uploading an unintended file via vectors involving a "dropped file." Opera anterior a la v10.00 sobre Linux, SOlaris y FreeBSD no implementa adecuadamente la funcionalidad "INPUT TYPE=file", lo que permite a atacantes remotos engañar al usuario para que suba un archivo a través de vectores que involucran un "archivo para descargar" (dropped file). • http://www.opera.com/docs/changelogs/freebsd/1000 http://www.opera.com/docs/changelogs/linux/1000 http://www.opera.com/docs/changelogs/solaris/1000 http://www.opera.com/support/kb/view/931 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A5679 • CWE-20: Improper Input Validation •
