CVE-2010-2233: Input Validation
First published: Wed Jun 23 2010(Updated: )
A flaw was found in a way libtiff handled vertically flipped (i.e. with negative toskew) images on 64bit platforms. Numeric computation used to calculate buffer pointer was done in the way that incorrectly extended from 32bit type to 64bit, resulting in out-of-bounds writes.
