The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the user when certain fatal errors occur, even if display_errors is off, which allows remote attackers to obtain sensitive information by causing the application to exceed limits for memory, execution time, or recursion. La función var_export en PHP v5.2 anterior a v5.2.14 y v5.3 anterior a v5.3.3 vacía el búfer de salida para el usuario cuando se producen ciertos errores graves, incluso cuando display_errors está apagado, lo que permite a atacantes remotos obtener información sensible provocando que la aplicación exceda los límites de memoria, tiempo de ejecución, o recursividad. • http://lists.apple.com/archives/security-announce/2010//Aug/msg00003.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2010-10/msg00000.html http://marc.info/?l=bugtraq&m=130331363227777&w=2 http://marc.info/?l=bugtraq&m=133469208622507&w=2 http://secunia.com/advisories/42410 http://support.apple.com/kb/HT4312 http:/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
