Why one would review 1.3 instead of 1.5.1 or 2.0 escapes my mind.

[Bug 711061] Re: [MIR] libopenjpeg2

2013-08-29 Thread Till Kamppeter
Looks like that the openjpeg project is dead upstream, leaving us with
no maintained free software JPEG2000 support (Jasper already died much
earlier). I hope Artifex (upstream of Ghostscript) will kick in here.

If not, anyone volunteering is welcome.

For now we must consider Ghostscript providing its own internal JPEG2000
support.

See IRC chat with GS developers:

tkamppeter chrisl, I switched back to built-in openjpeg, as I did not get it 
working with the system's library (GS simply built without openjpeg, without 
reporting any error).
chrisl tkamppeter: it might fallback to Jasper, or might just disable JPX, I 
can't remember off the top of my head.
tkamppeter chrisl, seems that openjpeg is of a rather bad coding quality: 
https://bugs.launchpad.net/ubuntu/+source/openjpeg/+bug/711061, especially 
comment #19. Are the enhancements of the GS developers (which upstream is 
ignoring/rejecting?) fixing these problems?
kens tkamppeter : the 2.0 patches have not yet been submitted upstream I was 
incorrect in that. The developer is waiting until we adopt them ourselves I 
believe (at least the ones relating to GS code anyway)
kens I think a lot of the criticisms in comment #19 are irrelvant to its use 
in Ghostscript
chrisl kens, tkamppeter: actually, he's waiting for responses (of any kind!) 
from the openjpeg devs. they've gone dark again :-(
kens tkamppeter : when it comes to JPEG2000 support we have a choice of 
JasPer or OpenJPEG. JasPer is terribly badly written, does not support all 
features, and is no longer maintained. OpenJPEG may not be ideal, but we htink 
its better than JasPer on all points.
chrisl tkamppeter: henrys has already suggested we really fork openjpeg for 
our use, since the project seems decidedly moribund now :-(
kens is disappointed to hear that
chrisl Well, I think Shelly's been waiting ~3 weeks for a reply to a simple 
question, and not even had an acknowledgement from the dev team
kens Great, 2 open source implementations, both dead :-(
chrisl I still have the feeling that OPJPG devs had their own requirements, 
and once those were met, they've backed off. I could wrong though
tkamppeter chrisl, so I think, to get solid JPEG2000 support into Linux/free 
software it would be really the best if Artifex forks libopenjpeg and makes it 
available as separate free software project.
kens Umm, I'm not sure we have the resources to support a 'proper' OpenJPEG 
library
chrisl tkamppeter: the trouble is it's a *lot* of work.
chrisl tkamppeter: we might be able to manage the project, host the repo 
etc, but the development load would probably be more that we could handle

2013-08-29 Thread Seth Arnold
Albert, when I reported vulnerabilities to the developers and other
distribution vendors, I tracked down many of the issues in the openjpeg
trunk/ branch in subversion. The worst of the offenses have not yet been
corrected in newer releases.

If you care about the openjpeg codebase and want to see its wider
adoption, please consider getting a Coverity account to perform a
detailed and thorough analysis. I only took a day or so of time to
review code and reviewed by hand. Probably the Coverity team can point
out far more issues to correct than I can.

[Bug 711061] Re: [MIR] libopenjpeg2

2013-08-28 Thread Seth Arnold
I reviewed openjpeg 1.3+dfsg-4.6ubuntu2 from saucy. This should not
be considered a full security audit, but rather a quick gauge of code
cleanliness.

- openjpeg provides a library interface and command line utilities for
  manipulating jpeg2000 formatted files.
- build-deps upon libtiff-dev
- Does not use cryptography, does not itself do networking
- Does not daemonize
- Does not provide initscripts
- Does not provide D-Bus services
- Does not provide setuid executables
- Provides four programs
  - index_create
  - jp2-thumbnailer
  - image_to_j2k
  - j2k_to_image
- Does not provide sudo fragments
- Does not provide cron jobs
- Messy build logs, most warnings can be safely ignored but these may be
  serious:
  - signedness error mistakes in j2k_index_JPIP() and one program's main()
  - 'tmp' may be used uninitialized in j2k_read_sot()
- Frequent casting of malloc(3)'s return value defeats compiler warnings
- Incorrect function prototyping defeats compiler warnings
- I did not discover a test suite.

[ Details redacted until 2013-09-09 -- sarnold 2013-08-28 ]
- cio_*() family of routines never check out-of-bounds reads and writes
  before the allocated buffer, even though cursor manipulations frequently
  rewind the cursor. I'm surprised such an obvious reliability measure is
  missing.

I have applied for CVE numbers.

I stopped auditing this package part-way through, so the above list of
problems is not exhaustive. This package needs a severe overhaul.

Security team NAK for promoting to main.

Thanks

CVE-2012-3358 is now fixed, but in the meantime, CVE-2012-3535 was
discovered. This makes 4 CVEs for its history, 2 within the period of
when I have gotten involved in the MIR, which is not building confidence
in the software. CVE-2012-3535 needs to be fixed before (re)considering

- CVE-2009-5030
- CVE-2012-1499
- CVE-2012-3358

There is an open security issue in openjpeg right now: bug #1023259
(CVE-2012-3358). This will have to be fixed before promoting openjpeg.

2012-06-15 Thread Albert Astals Cid
Ok, so some answers here:

Does libjpeg provide the same openjpeg does?
No, libjpeg is for regular jpeg and openjpeg is for jpeg2000 that has nothing 
to do with the first one other than the name

Can you provide an image that needs openjpeg?
No, but i can provide a pdf file that poppler needs openjpeg to be linked in to 
be renderer properly 
https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/881407/+attachment/2571595/+files/Manning-ExtJS_in_Action.pdf
Actually i had some images openjpeg opens and jasper does not, they are buried 
somewhere deep down in some kde mailing list if you really need them

Embedded tiff?
As far as i know it's just for windows developers convenience, they are only 
used if not found on your system. At least when compiling openjpeg 1.5 with 
cmake i get
-- Found ZLIB: /usr/lib/x86_64-linux-gnu/libz.so (found version 1.2.3.4)
-- Your system seems to have a Z lib available, we will use it to generate PNG 
lib
-- Found PNG: /usr/lib/x86_64-linux-gnu/libpng.so 
-- Your system seems to have a PNG lib available, we will use it
-- Found TIFF: /usr/lib/x86_64-linux-gnu/libtiff.so 
-- Your system seems to have a TIFF lib available, we will use it
-- Found LCMS2: /usr/lib/x86_64-linux-gnu/liblcms2.so 
-- Your system seems to have a LCMS2 lib available, we will use it

We already have jasper in main that is a jpeg2000 library?
Right, but poppler does not have code for jasper and jasper last release seems 
to be in 2007 and openjpeg is actively developed and released

Anymore thing you guys need answering?

- the sources contain an embedded libtiff. is it needed? is it used for
the build?

- the libjpeg8 source README reads:


FILE FORMAT WARS


The ISO JPEG standards committee actually promotes different formats like
JPEG 2000 or JPEG XR which are incompatible with original DCT-based
JPEG and which are based on faulty technologies.  IJG therefore does not
and will not support such momentary mistakes (see REFERENCES).
We have little or no sympathy for the promotion of these formats.  Indeed,
one of the original reasons for developing this free software was to help
force convergence on common, interoperable format standards for JPEG files.
Don't use an incompatible file format!
(In any case, our decoder will remain capable of reading existing JPEG
image files indefinitely.)
