Fedora 13 : mingw32-libtiff-3.9.5-1.fc13 (2011-5955)

Synopsis :

The remote Fedora host is missing a security update.

Description :

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.
