Note that there are two related bugs with two individual patches, the first reported Jan 2009 that indicates it resolves the root cause of the underflow rather than the infinite loop when it comes up. The older bug report is here: http://bugzilla.maptools.org/show_bug.cgi?id=1985 with the patch for bug #1985 being: http://bugzilla.maptools.org/attachment.cgi?id=279 vs the patch for bug #2065 being: http://bugzilla.maptools.org/attachment.cgi?id=314 kfax (kdegraphics) in Red Hat Enterprise Linux 3 includes embedded copy of the libtiff library, but it does not support LZW-encoded tiff images. For further details, see: https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2008-2327#c14 Hmm, the patch at upstream bug 1985 appears to prevent the crash, and it's a much more desirable fix than the one at 2065, because it results in a complaint about the image being corrupt instead of just silently bogus output. I wonder why Frank didn't apply that one? I'll try to ping him privately about it. Common Vulnerabilities and Exposures assigned an identifier CVE-2009-2285 to the following vulnerability: Buffer underflow in the LZWDecodeCompat function in libtiff 3.8.2 allows context-dependent attackers to cause a denial of service (crash) via a crafted TIFF image, a different vulnerability than CVE-2008-2327.
