生化危機(jī)5彈出提示框ERR08:memory overrun
內(nèi)存不足吧,你的處理器是不是有點(diǎn)低...memory overrun內(nèi)存溢出已經(jīng)是軟件開發(fā)歷史上存在了近40年的“老大難”問題,象在“紅色代碼”病毒事件中表現(xiàn)的那樣,它已經(jīng)成為黑客攻擊企業(yè)網(wǎng)絡(luò)的“罪魁禍?zhǔn)住薄?如在一個(gè)域中輸入的數(shù)據(jù)超過了它的要求就會(huì)引發(fā)數(shù)據(jù)溢出問題,多余的數(shù)據(jù)就可以作為指令在計(jì)算機(jī)上運(yùn)行。據(jù)有關(guān)安全小組稱,操作系統(tǒng)中超過50%的安全漏洞都是由內(nèi)存溢出引起的,其中大多數(shù)與微軟的技術(shù)有關(guān)。
為了便于理解,我們不妨打個(gè)比方。緩沖區(qū)溢出好比是將十磅的糖放進(jìn)一個(gè)只能裝五磅的容器里。一旦該容器放滿了,余下的部分就溢出在柜臺(tái)和地板上,弄得一團(tuán)糟。由于計(jì)算機(jī)程序的編寫者寫了一些編碼,但是這些編碼沒有對(duì)目的區(qū)域或緩沖區(qū)——五磅的容器——做適當(dāng)?shù)臋z查,看它們是否夠大,能否完全裝入新的內(nèi)容——十磅的糖,結(jié)果可能造成緩沖區(qū)溢出的產(chǎn)生。如果打算被放進(jìn)新地方的數(shù)據(jù)不適合,溢得到處都是,該數(shù)據(jù)也會(huì)制造很多麻煩。但是,如果緩沖區(qū)僅僅溢出,這只是一個(gè)問題。到此時(shí)為止,它還沒有破壞性。當(dāng)糖溢出時(shí),柜臺(tái)被蓋住。可以把糖擦掉或用吸塵器吸走,還柜臺(tái)本來面貌。與之相對(duì)的是,當(dāng)緩沖區(qū)溢出時(shí),過剩的信息覆蓋的是計(jì)算機(jī)內(nèi)存中以前的內(nèi)容。除非這些被覆蓋的內(nèi)容被保存或能夠恢復(fù),否則就會(huì)永遠(yuǎn)丟失。
在丟失的信息里有能夠被程序調(diào)用的子程序的列表信息,直到緩沖區(qū)溢出發(fā)生。另外,給那些子程序的信息——參數(shù)——也丟失了。這意味著程序不能得到足夠的信息從子程序返回,以完成它的任務(wù)。就像一個(gè)人步行穿過沙漠。如果他依賴于他的足跡走回頭路,當(dāng)沙暴來襲抹去了這些痕跡時(shí),他將迷失在沙漠中。這個(gè)問題比程序僅僅迷失方向嚴(yán)重多了。入侵者用精心編寫的入侵代碼(一種惡意程序)使緩沖區(qū)溢出,然后告訴程序依據(jù)預(yù)設(shè)的方法處理緩沖區(qū),并且執(zhí)行。此時(shí)的程序已經(jīng)完全被入侵者操縱了。
入侵者經(jīng)常改編現(xiàn)有的應(yīng)用程序運(yùn)行不同的程序。例如,一個(gè)入侵者能啟動(dòng)一個(gè)新的程序,發(fā)送秘密文件(支票本記錄,口令文件,或財(cái)產(chǎn)清單)給入侵者的電子郵件。這就好像不僅僅是沙暴吹了腳印,而且后來者也會(huì)踩出新的腳印,將我們的迷路者領(lǐng)向不同的地方,他自己一無所知的地方。
緩沖區(qū)溢出的處理
你屋子里的門和窗戶越少,入侵者進(jìn)入的方式就越少……
由于緩沖區(qū)溢出是一個(gè)編程問題,所以只能通過修復(fù)被破壞的程序的代碼而解決問題。如果你沒有源代碼,從上面“堆棧溢出攻擊”的原理可以看出,要防止此類攻擊,我們可以:
1、開放程序時(shí)仔細(xì)檢查溢出情況,不允許數(shù)據(jù)溢出緩沖區(qū)。由于編程和編程語言的原因,這非常困難,而且不適合大量已經(jīng)在使用的程序;
2、使用檢查堆棧溢出的編譯器或者在程序中加入某些記號(hào),以便程序運(yùn)行時(shí)確認(rèn)禁止黑客有意造成的溢出。問題是無法針對(duì)已有程序,對(duì)新程序來講,需要修改編譯器;
3、經(jīng)常檢查你的操作系統(tǒng)和應(yīng)用程序提供商的站點(diǎn),一旦發(fā)現(xiàn)他們提供的補(bǔ)丁程序,就馬上下載并且應(yīng)用在系統(tǒng)上,這是最好的方法。但是系統(tǒng)管理員總要比攻擊者慢一步,如果這個(gè)有問題的軟件是可選的,甚至是臨時(shí)的,把它從你的系統(tǒng)中刪除。舉另外一個(gè)例子,你屋子里的門和窗戶越少,入侵者進(jìn)入的方式就越少。
