Type/Severity
Security Advisory: Moderate
Topic
An update for libtiff is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
Description
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-2016-9533, CVE-2016-9534, CVE-2016-9535)
- Multiple flaws have been discovered in various libtiff tools (tiff2pdf, tiffcrop, tiffcp, bmp2tiff). 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. (CVE-2015-8870, CVE-2016-5652, CVE-2016-9540, CVE-2016-9537, CVE-2016-9536)
