This update for ImageMagick fixes the following issues:

• CVE-2016-9556 Possible Heap-overflow found by fuzzing [bsc#1011130]
• CVE-2016-9559 Possible Null pointer access found by fuzzing [bsc#1011136]
• CVE-2016-8707 Possible code execution in Tiff conver utility [bsc#1014159]
• CVE-2016-8866 Memory allocation failure in AcquireMagickMemory could lead to Heap overflow [bsc#1009318]
• CVE-2016-9559 Possible Null pointer access found by fuzzing [bsc#1011136]

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
