Problems with new fc_internal_rar

#1 Post by Timon » 04.11.2014, 14:38

FC XE 674

If we try even to open (with Ctrl-PageDown or Enter key) any rar file (version 4 or 5) not only with password protection, but also encrypted, we see error message Access violation at address 008AB234 in module FreeCommander.exe. Read of address 00000142.

Can you provide an example file, please (only if it's not sensitive data)?
I found a few password protected rar files and they open fine, but I don't know if they were version 5 (any way to check that without Winrar 5?).

P.S. I got a similar error while trying to open a zip file, but it turned out to be an incomplete downloaded file (corrupted archive).

Test file in RAR5 format with password and encryption http://my-files.ru/zsjx8j
Test file in RAR4 format with password and encryption http://my-files.ru/67e82f

Password for both archives - 1.
In each archive there are 5 text files. Files were created with original WinRAR.

Thanks for the samples!

There are not many apps at this moment that are able to open RAR5 archives (I used IZArc for these), but there shouldn't be any problem with RAR4 or lower version rar archives, encrypted or not.

This is the error I get on execute in both cases using FC XE 675 x86 and x64 with default settings on win7x64sp1 OS:

When using Alt+F6 I get "Data load error" window (and sometimes FC crash, with bug report sent).

Is the password '- 1' or '- 1.' or '1.' - nothing works with Winrar.

It's "1" (just the number, no quotes).

Use one of the following:
B1 - http://www.b1.org
Bandizip - http://www.bandisoft.com/bandizip/

They work even with RAR5 format without any problems and they are absolutely free.

Also it would be nice to create some "mechanism" for automatic update of unrar.dll for each new version of FC XE. Winrar is quite actively developed. At the moment, already published much more recent version of unrar.dll - 5.20.3.1404, which was available when FC XE 675 was released - http://www.rarlab.com/rar/UnRARDLL.exe

New problem!!!

Now encrypted+password protected files are opened and unpacked fine, BUT password for opening archive is remembered till FC XE session end (password is required only 1 time)

Try to open any such archive (for example, RAR5-pass_encrypt.rar). Unpack files from archive to any folder, go to any other file or folder, unpack something else and after that return to RAR5-pass_encrypt.rar and try to open it. There is no password request and file is opened without it! It is a serious vulnerability.

And another one problem with internal RAR support in FC XE 680

Create any folder (for example, TEST). Copy any encrypted and password protected RAR file in it (for example, RAR5-pass_encrypt.rar - you can find it here - http://my-files.ru/zsjx8j)
Run Search files/folders
File name: 1.txt
Folders: C:\TEST
Search in archives is set to ON
For request "Password needed" press Cancel button.
No files or folders would be found, BUT font size for some elements became much bigger (all columns in Search results: Name, Found in, Size, Modified, ...)
If you close "Search files/folders" dialog and open it again, you'll see that font size of all elements become much bigger (except tab names).

The only way to solve the problem - restart FC.

There is no such problem with Total7Zip plugin and 7z encrypted and password protected files.

I'm not able to search inside encrypted .rar archives (I get no request for password during the search process). Is it just me?

You are right @joby_toss
In 681 search inside encrypted and password protected archives is broken vs version 680. There is no password request any more.

For RAR password protected archives (NOT encrypted) there is password request while search.
For all 7z password protected archives (encrypted and not encrypted) there is password request while search.

Run Unpack... (Alt+F6)
to any Target
There would be password request 2 times. Enter correct password 2 times (it is one digit - 1)
All files would be unpacked.
BUT in you press Unpack... (Alt+F6) one more time, you'll see that font size of all elements become much bigger (except tab names).
