Sun JAVA insecure file creation + IEA seemingly trivial vulnerability has been found in the latest Sun JAVA virtual machine. Details about the vulnerability: » www.illegalaccess.org/cm ··· e/view/9Note one post on the Full Disclosure mailing list: quote: There's a very minor issue with the way the sun java virtual machine creates temporary files from applets. IE blows it off the chart, combining this with some unresolved issues in IE can lead to remote code execution

I guarantee this is exactly what I have been trying to nail down for the past week or so. However the browser crashes in IE and Firefox: » JS.ModalDZoneBypass.exploit nails SP2...» [Help] FireFox SSL Settings? |

I mentioned IE because of the combined vulnerability. Of course you are right, every browser with Sun JAVA virtual machine plugin is vulnerable to this.
IF you click "skip" in the JAVA exception dialog, the browser does not crash. |

I just installed SunJava 1.4.2_4. Does it have this vulnerability? I also have it set not to store anything in the cache, will that avoid this problem? Thanks. Sincerely, Libra |

Yes, unfortunately Sun Java 1.4.2_04 is still vulnerable. And the file gets created in the temp directory no matter if caching is on or off. |

Any ideas when they will fix this one? |

I just downloaded version 1.4.2_05 yesterday. How can I check to see if it's vunerable? |

Rdax , This is listed almost the end of this page » seclists.org/lists/fulld ··· 434.htmlquote: DEMO
»poc.homedns.org/execute.htm
I get nothing but a blank screen with Java disabled. It is suggested that Java be disabled until a patch is released: quote: Solution Until a patch becomes available, disable Java by going to: File -> Preferences -> Multimedia, and uncheck the "Enable Java" item. »www.illegalaccess.org/cm ··· e/view/9

Just out of curiosity, where did you find 1.4.2_ 05? |

Thanks! Incidentally, I already have J2SE v 1.4.2_0 4. I may need glasses but I don't see a reference to _05 on this page. |

Is SunJava 1.4.1_5 subject to this vulnerability? I just found out a bug in 1.4.2._2 is causing my computer to hang when I attempt to shut down. If 1.4.1_5 is okay, where can I find it? Thank you. Sincerely, Libra |

Tablet, thank you for your reply. If you don't have the cache set up, where is the temp directory? i.e., would an AV find it? I remember reading where someone had malware and it was located in the jar of SunJava. I was hoping to by-pass that. Thank you. Sincerely, Libra |

The tmp file gets stored in "%userprofile%\Local Settings\Temp". An AV would be able to detect the file if it would be a known virus. |

Thanks to Goldengamego( I do need glasses!) and Cudni. I now have the Java(TM) Plug-in 1.4.2_05 installed with java enabled in Firefox. This is what I see: 1.) No crash in Tablet's above referenced vulnerability test. 2.) *.tmp files still created from test (+~JF23126.tmp, 500 bytes) 3.) from the jusched.log located in the same \TMP folder: Sun Jul 11 04:36:13 2004 :: Either not a Win2000, XP platform or Non-admin user or GetModuleFilename failed or Error Opening JavaUpdate Keys.
What should I make of this? Incidentally, thank you Tablet for highlighting this important alert. --- WINXP SP1 Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040710 Firefox/0.9.0+ (stipe) |

Would the temp file go to Windows/Temp or Windows/Temporary Internet Files? And how do these files get cleared? (I just did a search for local settings in Find, and 35 items came up.) Thanks again. Sincerely, Libra |
