Summary
ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the TIFF encoder when an invalid tiff:tile-geometry is specified. Supplying malformed tile geometry parameters causes allocated memory not to be released, which can lead to increased memory consumption.
A flaw was found in ImageMagick. A local user can exploit this vulnerability by supplying malformed tile geometry parameters to the TIFF encoder.
This can cause a memory leak, preventing allocated memory from being released. The primary consequence is increased memory consumption, which may lead to a Denial of Service (DoS) condition.
Red Hat Enterprise Linux ships ImageMagick in RHEL 6 ELS and RHEL 7 ELS. This flaw has been rated as having a Low security impact and is not currently planned to be addressed in future updates of those products.

Mitigation checklist
- Do not process untrusted image files with ImageMagick. If processing of untrusted input is required, configure ImageMagick's policy.xml to set memory and map resource limits to contain the impact of potential memory leaks. Upgrade to ImageMagick 7.1.2-26 or 6.9.13-51 mitigates the issue.
