Multiple* bug's associated with Win xp default zip Manager...







1).

---DESCRIPTION---

 Win xp default zip manager prompt's for a password, [even* when there is 

no password] if the zipped file has folder/s with more than 121 sub 

directories in it, but this situation does vary with some condition as 

specified below...



---Bug Demonstration---

---------------

Create a batch script (*.bat)

---------------

 :lol

 md 1

 cd 1

 goto lol

-------------

[OR, download] http://www.geocities.com/visitbipin/winxp_zip_bug.zip



 If you "execute" this batch script [*.bat] from your root, [ ie   c:\  ] 

windows can at-most create 121'th sub directory, ie \..\1\1\1\..\...[upto 

121'th sub directory,] then the batch script ends with a error messages...



 Now say if i put "md 12" instead of "md 1" to the above script, [ie two 

characters 

 Directory name instead of one"] windows can at most create... 80 sub 

directory!



 Again, say if i put md 12345 ->"five character directory name in the 

same way..."<- 

 windows can at most create... 39 sub directory!



 HENCE, IF you simply ZIP A FILE WITH SAY 39 SUB-DIRECTORY in it with 5 

character directory name as explained in the above demonstration [ie: md 

12345 ] Win xp default zip manager prompts for a password in extraction 

process [copy the 12345.zip file to c:\windows\system32 and try 

extracting it there] but when you use a third party software, it simply 

ends up with an error. [as windows has restrictions on creating number of 

sub - directories which is proportional to the number of characters used 

to label a folder!]



Moreover it even prompt for password to file names that doesn't exists!



---Conclusion---

Concluding from the experiment conducted from LINUX, on a fat32/ntfs 

partition, it seems the problem isn't with the "file system itself" but 

it occurs due to the restriction of windows!

2).

---Description---

Win xp default zip manager can't handle long file names properly...



---Bug Demonstration---

Create a new file with very long file name... in your c:\

 [ say:

1.111111111111111111111111111111111111111111111111111111111111111111111111

11111111111111111111111111111111111111111111111111111111111111111111111111

11111111111111111111111111111111111111111111111111111111111111111111111111

11111111111111111111111111111 ] 



[or, download]   http://www.geocities.com/visitbipin/zip_long.zip



Windows xp will easily allow you to create that file, now zip the file [ 

above mentioned ie 1.11111111111111111111* ] using winxp default zip 

manager, [say, the new file created is 1.zip]

But strangely, if you open the file [1.zip] with windows explorer [ie 

view it's content] You can neither see a file name nor its extension in 

the archive but simply its icon only!



Moreover, windows xp doesn't allow you to delete the long file created in 

the above example, through GUI mode [...have to use command prompt] and 

end up with an error Can't delete 1 : The folder is empty. [actually its 

a file!]

3).

---Description---

A probable buffer overflow with winxp default zip manager! [zipfldr.dll]



---Demonstration---

http://www.geocities.com/visitbipin/hUNTER_.zip



Well, as win xp automatically creates a bug report of a crash, the bug is 

self explanatory.

Simply try extracting the above file using win xp default zip manager or 

try viewing the file hUNTER_..PKT YOUR EXPLORER WILL CRASH!
