Synopsis:          Important: libtiff security and bug fix update
Issue date:        2011-03-29
CVE Names:         CVE-2011-1167

A heap-based buffer overflow flaw was found in the way libtiff processed
certain TIFF files encoded with a 4-bit run-length encoding scheme from
ThunderScan. 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-2011-1167)

This update also fixes the following bug:

* A prior libtiff update introduced a regression that prevented
certain TIFF Internet Fax image files, compressed with the CCITT Group 4
compression algorithm, from being read. (BZ#688825)
