Red Hat: RHSA-2017-0225 Moderate: libtiff Memory Corruption Risk

red hat
Calendar Grey February 1, 2017
Scroller Redhat
Targeted libtiff revisions for CentOS to resolve memory leaks and stability problems. Implement suggested patches.
An update for libtiff is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

All running applications linked against libtiff must be restarted for this update to take effect.

Summary

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)
