Description Tomas Hoger 2010-06-14 07:49:29 EDT
Description of problem:
Yet another "crasher" from Sauli Pahlman reported in Launchpad:

Unknown tag can cause libtiff to abort program execution in tif_dirinfo.c _TIFFFieldWithTag (or _TIFFFieldWithName) due to failed assertion failure.  This can be tested with e.g. tiff2rgba on the test image file.

Version-Release number of selected component (if applicable):

Additional info:
This issue does not affect libtiff in RHEL-3/4/5.  Even though problematic assert is part of upstream sources of older libtiff versions, it was removed from RHEL packages via libtiff-*-ormandy.patch added in RHSA-2006:0603 (see bug #199111).

Removing assert causes libtiff to try to deref NULL on multiple places.

Comment 4 Tom Lane 2010-06-14 11:33:39 EDT
This turns out to be already fixed in my local copy of 3.9.2, as a result of the patch I submitted for our bug #554371 (see http://bugzilla.maptools.org/show_bug.cgi?id=2210).  I haven't tested yet to see if it affects 3.8 or before.
Comment 5 Tomas Hoger 2010-06-15 06:40:01 EDT
There's not assert abort with libtiff-unknown-tags.patch applied.
Comment 6 Tomas Hoger 2010-06-22 03:18:21 EDT
Making this public, as there is public upstream bug for the issue.

Actually, this should be a crash described as CVE-2010-2631.
