PHP Mb_Parse_Str函数Register_Globals激活漏洞

PHP是一款广泛使用的WEB开发脚本语言。

PHP不正确处理内存限制异常问题，远程攻击者可能利用此漏洞激活register_globals’，可导致进一步对系统进行攻击。

当mb_parse_str()函数仅使用一个参数调用时会内部激活egister_globals，这个激活操作通过直接在内存中操作标记来完成，没有进入帐户memory_limit中断：

if (info->force_register_globals) {
    prev_rg_state = PG(register_globals);
    PG(register_globals) = 1;
}

如果脚本终止发生直到标记被重设，那么它不会自动恢复，通过触发memory_limit冲突可导致激活不被关闭而导致其他攻击。
