Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function. Múltiples vulnerabilidades de formato de cadena en la extensión phar en PHP v5.3 anterior a v5.3.2, permite a atacantes dependientes del contexto obtener información sensible (contenido de la memoria) y posiblemente ejecutar código de su elección a través de una URI phar:// que no se ha manejado adecuadamente por las funciones (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, o (4) phar_wrapper_open_url en ext/phar/stream.c; y la función (5) phar_wrapper_open_dir en ext/phar/dirstream.c, que provoca un error en la función php_stream_wrapper_log_error. • https://www.exploit-db.com/exploits/33988 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2010-10/msg00000.html http://php-security.org/2010/05/14/mops-2010-024-php-phar_stream_flush-format-string-vulnerability/index.html http://php-security.org/2010/05/14/mops-2010-025-php-phar_wrapper_open_dir-format-string-vulnerability/index.html http://php-security.org/2010/05/14/mops-2010-026-php-phar_wrapper_unlink-f • CWE-134: Use of Externally-Controlled Format String •
