Calendar Grey August 2, 2016
Scroller Redhat
Red Hat has issued a significant security patch for libtiff, correcting several vulnerabilities. Discover further details.
An update for libtiff is now available for Red Hat Enterprise Linux 6

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-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. (CVE-2014-8127, CVE-2014-8129, CVE-2014-8130, CVE-2014-9330, CVE-2015-7554, CVE-2015-8668, CVE-2016-3632, CVE-2016-3945, CVE-2016-3991)
