Description Tomas Hoger 2010-07-06 19:03:09 UTC
The TIFFReadDirectory function in LibTIFF 3.9.0 does not properly
validate the data types of codec-specific tags that have an
out-of-order position in a TIFF file, which allows remote attackers to
cause a denial of service (application crash) via a crafted file, a
different vulnerability than CVE-2010-2481.

Comment 1 Tomas Hoger 2010-07-07 09:11:47 UTC
This particular symptom of unknown / out-of-order tag handling issues did not affect current libtiff packages in Red Hat Enterprise Linux 3, 4 and 5 due to previously applied patch (libtiff-*-ormandy.patch).  Future libtiff updates will improve that patch to use approach from patch submitted in the upstream bug report #2210.  The fix is already included in Fedora 3.9.4-1 packages.

Statement:

Not vulnerable. This issue did not affect the versions of libtiff as shipped with Red Hat Enterprise Linux 3, 4, or 5.
