Full Text Bug Listing

The jpc_qcx_getcompparms function in jpc/jpc_cs.c for the JasPer
JPEG-2000 library (libjasper) before 1.900 allows remote user-assisted
attackers to cause a denial of service (crash) and possibly corrupt
the heap via malformed image files, as originally demonstrated using
imagemagick convert.

sci please advise.

Hi guys,

Thanks for the heads-up!

I just had a look at bug #413041 in Debian's bugzilla and
what a mess!
In any case, I just pushed out jasper-1.900.1-r1 which 
has as the fix for the overflow in jpc/jpc_cs.c. This addresses
the problems with the testfiles broken2.jp2 and broken4.jp2
as posted in Debian's bugzilla. However, the other ones
(broken.jpc, ..) still cause segfaults on my x86 box and
are still unresolved in debian as well AFAIKT.

How should we proceed from here? 

Thanks,
Markus

My apologies, I didn't mean to close this one at all :(
I don't know what happened! Reopening.....

Markus

I guess you checked "Resolve bug" before comitting:)

Markus do you have any idea about a possible timeframe for the remaining fixes?

The issue doesn't seem too serious so I'd rather avoid calling arches twice if
it's not needed.

Unfortunately, I don't know jasper well at all so I don't really
have a time frame yet for when the rest will be fixed and by
whom. I'll keep an eye on debian's bugzilla for any progress.

I suspect that the best way to proceed would be to ping 
upstream, make them aware of the problems (not sure
if this has happened yet) and hope they will provide an
updated release that fixes these issues. I'll ping them later
and post back with any news.

Thanks,
Markus

Markus, any news? Otherwise I'll call arches.

Hi Sune,

Sorry for the delay! I just heard back from upstream 
and here's what they have to say

I will add your email to my work queue for JasPer.
Since I do not have much time to work on JasPer
these days, it may take a while before I can
resolve the issues mentioned in your email.

----------- SNIP -------------------------------------------------

Sounds to me as if the remaining issues won't get
resolved in the very near future. Nothing has happened
over at debian regarding the remaining issues either
AFAICT. Hence, maybe we should just go ahead and
push out what we have so far. What do you think?

Best,
Markus

Thx Micheal, lets get this stabled.

Arches please test and mark stable. Target keywords are:

jasper-1.900.1-r1.ebuild:KEYWORDS="alpha amd64 arm hppa ia64 mips ppc ppc64
s390 sh sparc x86 ~x86-fbsd"

media-libs/jasper-1.900.1-r1  USE="jpeg opengl"

1. emerges on x86
2. passes test suite
3. passes collision test
4. works

For me Stable in x86

The update breaks ABI thus it would be nice to have a big fat usual
"revdep-rebuild" warning sticked to it. It breaks digikam at least.

Markus please provide an updated elog warning.

Arches I guess you can just continue stable marking.

Stable for HPPA.

sparc stable and added the note myself.

Thanks much! Unfortunately, I wasn't aware of the ABI break.
I really wonder if I should ask the graphics folks if they
would be willing to take over this package since the sci herd 
doesn't quite seem like its proper home:)

Best,
Markus

sorry for the delay, amd64 stable, thanks Kenneth

I vote NO.

"possible?" just "crash"? Then i vote noglsa
