Fedora Update Notification
FEDORA-2011-5955
2011-04-25 20:22:54
--------------------------------------------------------------------------------

Name        : mingw32-libtiff
Product     : Fedora 13
Version     : 3.9.5
Release     : 1.fc13
URL         : http://www.remotesensing.org/libtiff/
Summary     : MinGW Windows port of the LibTIFF library
Description :
The libtiff package contains a library of functions for manipulating
TIFF (Tagged Image File Format) image format files.  TIFF is a widely
used file format for bitmapped images.  TIFF files usually end in the
.tif extension and they are often quite large.

The libtiff package should be installed if you need to manipulate TIFF
format image files.

--------------------------------------------------------------------------------
Update Information:

Update MinGW Windows cross-compiled libtiff to 3.9.5, incorporating most of
our previous patches.

Includes a fix for CVE-2011-1167: 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.
