An update for libtiff is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
Security Fix(es) :
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)
Multiple flaws have been discovered in various libtiff tools (bmp2tiff, pal2rgb, thumbnail, tiff2bw, tiff2pdf, tiffcrop, tiffdither, tiffsplit, tiff2rgba). By tricking a user into processing a specially crafted file, a remote attacker could exploit these flaws to cause a crash or memory corruption and, possibly, execute arbitrary code with the privileges of the user running the libtiff tool.
