Description Ian Zimmerman 2016-09-12 03:39:11 UTC 
According to the RedHat summary [1]:

An out-of-bounds read vulnerability in CopyMagickMemory was found that can lead to memory leak because the read data are written into output image using SetImageProperty or can cause DoS by crashing the application.

Fixed by upstream as in [2], in version 6.9.5-4. The first version available in gentoo above that is 6.9.5-5, still keyworded as unstable.
