This update for GraphicsMagick fixes several issues.

These security issues were fixed:

• CVE-2017-11524: The WriteBlob function allowed remote attackers to cause a denial of service (assertion failure and application exit) via a crafted file (bsc#1050087)
• CVE-2017-16353: Prevent memory information disclosure in the DescribeImage function caused by a heap-based buffer over-read. The portion of the code containing the vulnerability is responsible for printing the IPTC Profile information contained in the image. This vulnerability can be triggered with a specially crafted MIFF file. There is an out-of-bounds buffer dereference because certain increments were never checked (bsc#1066170)
• CVE-2017-16352: Prevent a heap-based buffer overflow in the 'Display visual image directory' feature of the DescribeImage() function. One possible way to trigger the vulnerability is to run the identify command on a specially crafted MIFF format file with the verbose flag (bsc#1066168)
• CVE-2017-14314: Prevent off-by-one error in the DrawImage function that allowed remote attackers to cause a denial of service (DrawDashPolygon heap-based buffer over-read and application crash) via a crafted file (bsc#1058630)
• CVE-2017-14505: Fixed handling of NULL arrays, which allowed attackers to perform Denial of Service (NULL pointer dereference and application crash in AcquireQuantumMemory within MagickCore/memory.c) by providing a crafted Image File as input (bsc#1059735)
• CVE-2017-15016: Prevent NULL pointer dereference vulnerability in ReadEnhMetaFile allowing for denial of service (bsc#1082291)
• CVE-2017-15017: Prevent NULL pointer dereference vulnerability in ReadOneMNGImage allowing for denial of service (bsc#1082283)
• CVE-2017-12693: The ReadBMPImage function allowed remote attackers to cause a denial of service (memory consumption) via a crafted BMP file (bsc#1082348)
• CVE-2017-18219: Prevent allocation failure in the function ReadOnePNGImage, which allowed attackers to cause a denial of service via a crafted file that triggers an attempt at a large png_pixels array allocation (bsc#1084060)
• CVE-2017-18230: Prevent NULL pointer dereference in the function ReadCINEONImage, which allowed attackers to cause a denial of service via a crafted file (bsc#1085233).
• CVE-2017-18220: The ReadOneJNGImage and ReadJNGImage functions allowed remote attackers to cause a denial of service (magick/blob.c CloseBlob use-after-free) or possibly have unspecified other impact via a crafted file (bsc#1084062).

It was discovered that GraphicsMagick incorrectly handled certain image files. An attacker could possibly use this issue to cause a denial of service or other unspecified impact.
