Description

Multiple flaws have been discovered in libtiff. A remote attacker could exploit these flaws to cause a crash or memory corruption and, possibly, execute arbitrary code by tricking an application linked against libtiff into processing specially crafted files. (CVE-2014-9655 , CVE-2015-1547 , CVE-2015-8784 , CVE-2015-8683 , CVE-2015-8665 , CVE-2015-8781 , CVE-2015-8782 , CVE-2015-8783 , CVE-2016-3990 , CVE-2016-5320)
