Red Hat: RHSA-2016:1546-01 Important: LibTiff Memory Corruption Risk

red hat
Calendar Grey August 2, 2016
Scroller Redhat
An update has been released for libtiff affecting Red Hat Enterprise Linux 7, addressing significant security vulnerabilities and potential remote exploitation risks.
An update for libtiff is now available for 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-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)
