Description Kurt Seifried 2012-07-25 15:38:35 EDT
The libpng project announced that libpng 1.5.4 through 1.5.7 contain a 
one-byte (stack) buffer-overrun bug in png_formatted_warning(), which could 
lead to crashes (denial of service) or, conceivably, execution of hostile 
code. This vulnerability has been assigned ID CVE-2011-3464 and is fixed in 
version 1.5.8, released 1 February 2012.

Not vulnerable. This issue did not affect the versions of libtiff as shipped with Red Hat Enterprise Linux 4, 5, and 6.
