Description Jan Lieskovsky 2011-02-18 17:28:55 UTC
A heap-based buffer overflow was found in the way TIFF (Tagged Image File Format) image files manipulating library expanded certain rows of 2D-encoded data, when processing TIFF Internet Fax image files, compressed with CCITT group 4 compression algorithm. If an attacker created a specially-crafted image file and tricked a local, unsuspecting user into loading the image file in an application that uses the TIFF image manipulating library, it could cause that application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

Comment 23 Even Rouault 2011-03-08 19:25:51 UTC
This fix is believed to cause a regression when reading CCITFAX4 compressed TIFF file that could be read successfully before. See http://bugzilla.maptools.org/show_bug.cgi?id=2297
Comment 24 Tom Lane 2011-03-10 17:37:03 UTC
Sigh. Even is right: this fix is busted and will reject files that should be accepted, including some produced by libtiff itself. See analysis and corrected patch at the upstream bug linked in comment #23.
