RE: [Passwordsafe-users] "out of memory" error!

[Rony S. <ro...@gm...>]

Hi Karel,

That was my first thought too: I was thinking of diving into the code with a
debugger and manually changing the allocation to the correct value.

On second thought, however, if the length decrypts to garbage, chances are
that the whole file is corrupt.

Anyway, reading the length and allocating accordingly is done in _readcbc()
in Util.cpp:

   unsigned char* wholething = new unsigned char[BlockLength];

Hi,

This is Karel Van der Gucht
Is there any chance to limit the amount of memory allocated (e.g. twice the
amount of the file), to get a chance of loading and "resaving" the .dat
file, if the calculated amount of memory is out of reasonable scale?
This could help Hua in restoring his .dat file

We are using a version 1.9.4 (derived from 1.9.0, with an enhanced password
generating feature).

Hua:	I did send you the file 1.9.4, so you can test if this one is working.
	BUT: I'm pretty shure it won't, because I didn't change anything about
reading and storing files.
	After all, lets give it a try.

Rony:	do you know the area in the code of pwsafe where this allocation is
done, so I could give it a try on my suggestion.

mit freundlichen Grüßen, kind regards
Karlo Van der Gucht

Ah, that's better!

It indeed seems that the file in question got corrupted. Here's why: One of
the first things that's encrypted in the file is the length of the actual
data. This is read and decrypted, and memory is allocated accordingly. If
this is somehow corrupted, then a HUGE amount of memory is (trying to be)
allocated.

Hi Rony,

Thanks for your response.

Here are my answers for your questions:
1. version 1.7
2. everytime for that particular file.
3. 1KB
4. only that particular file, other files are fine.
5. only 3 entries.
6. I am using Window 2K Pro, 512MB ram. I have other large applications but
are fine.

My guess is that particular file might get somehow corrupted. But I donot
know how.
I appreciate your help on this.

Best Regards,
Will
