FireFox 3/2 爆發多重安全性漏洞!



FireFox 3.0FireFox 2.0今天被發現有同樣的多重安全性漏洞
這兩個版本均為高危安全漏洞!
正在使用這兩個版本的人應該盡速更新!


所幸漏洞在發現的同一天內Mozilla就釋出了修正檔

Description:
Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to bypass certain security restrictions, to disclose sensitive information, or to potentially compromise a user's system.

1) An error in the JavaScript move and resize functionality can be exploited to trick the user into clicking an unintended button and e.g. download a malicious file.

2) Multiple errors can be exploited to pollute "XPCNativeWrappers" and run arbitrary script code with Chrome privileges.

3) Multiple errors in "XSLT" and "document.loadBindingDocument()" while creating documents can be exploited to run arbitrary script code with Chrome privileges.

4) Multiple errors in the layout and JavaScript engines can be exploited to corrupt memory.

5) Two errors in the image rendering implementation can be exploited to cause a crash.

6) An error in the graphics rendering engine can be exploited to cause a crash.

Successful exploitation of vulnerabilities #4-#6 may allow execution of arbitrary code.

7) An error in the processing of BOM characters included in JavaScript code can be exploited to potentially bypass script filters and facilitate cross-site scripting attacks.

8) Multiple errors in the implementation of the "resource:" protocol can be exploited to perform directory traversal attacks and disclose sensitive information.

Successful exploitation of vulnerabilities #4-#6 may allow execution of arbitrary code.

The vulnerabilities are reported in versions prior to 3.0.2.


某些漏洞可以繞過程式本身的安全機制,甚至還可以透過Buffer OverFlow執行任意代碼!
所幸FireFox的使用者已經可以透過FireFox本身內建的更新功能進行升級
第一次見到如此即時的零天更新!因為這多重漏洞是在Mozilla發佈更新後才公佈出來的!

  4. 3.0.2不是修補一些漏洞而已嘛?怎麼會變快呢?

    回覆刪除
  5. @sheweeeeee

    有的時候修正漏洞或bug
    也會一併修正一些問題
    但是為什麼這個版本變快了
    可能要仔細研讀源碼才有可能知道
