Description Vincent Danen 2011-03-14 20:35:23 UTC
A flaw was reported in libtiff's thunder decoder.  The thunder decoder assumes 4bits per pixel, but if a file has bitpersample set to a smaller value, or defaulted (1) then the allocated strip buffer will be too small, and a heap-based buffer overlow may occur.  This could be used to crash an application linked to libtiff, or execute arbitrary code with the privileges of the application opening a malicious TIFF file.
