これは大量の修正だ・・・

Description:
Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to conduct cross-site scripting and spoofing attacks, bypass certain security restrictions, disclose sensitive information, or potentially compromise a user's system.
1) Multiple errors in the layout and JavaScript engines can be exploited to corrupt memory.
2) An error in the handling of unprivileged XUL documents can be exploited to load Chrome scripts from a "fastload" file via "<script>" elements.
3) An error in the "mozIJSSubScriptLoader.LoadScript()" function can be exploited to bypass XPCNativeWrappers and run arbitrary code with Chrome privileges.
Successful exploitation requires that an add-on using the affected function is installed.
4) An error in the block reflow process can be exploited to cause a crash or potentially execute arbitrary code.
5) An error in the processing of file URLs contained within local directory listings can potentially be exploited to execute malicious JavaScript content.
6) Multiple errors in the implementation of the JavaScript same origin policy can be exploited to execute arbitrary script code in the context of a different domain.
7) Multiple errors in the verification of signed JAR files can be exploited to execute arbitrary JavaScript code with the privileges of the JAR's signer.
8) An error in the implementation of file upload forms can be exploited to upload arbitrary local files to a remote webserver via specially crafted "DOM Range" and "originalTarget" elements.
9) An error in the Java LiveConnect implementation on Mac OS X can be exploited to establish arbitrary socket connections.
10) An uninitialized memory access in the processing of improperly encoded ".properties" files can potentially be exploited to disclose sensitive memory via an add-on using the malformed file.
11) An error in the processing of "Alt Names" provided by "peer" trusted certificates can be exploited to conduct spoofing attacks.
12) An error in the processing of Windows URL shortcuts can be exploited to run a remote site as a local file.

Successful exploitation requires that the user is tricked into downloading and then opening a malicious Windows URL shortcut.
The vulnerabilities are reported in versions prior to 2.0.0.15.

Security Advisory SA30911 - Mozilla Firefox Multiple Vulnerabilities - Secunia

@ITによると、Firefox3には影響はなさそうとのこと。でもFireFox3にある脆弱性についてはまだ修正されていないとのこと

悪用されるとリモートで任意のコードを実行されたりブラウザがクラッシュしたりするなどの影響がある。いずれの脆弱性Firefox 3では影響しないか、もしくは対処済みとなっている。

 なお、Firefox 3のリリース直後にもFirefox 3と2に影響する脆弱性が報告されているが、こちらはまだ修正されていないようである。
