A heap-based buffer overflow flaw was found in the way libtiff processed
certain TIFF Internet Fax image files, compressed with the CCITT Group 4
compression algorithm. An attacker could use this flaw to create a
specially-crafted TIFF file that, when opened, would cause an
application linked against libtiff to crash or, possibly, execute
arbitrary code. (CVE-2011-0192)
All running applications linked against libtiff must be restarted for
this update to take effect.
