CVE-2017-12693

The ReadBMPImage function in coders/bmp.c in ImageMagick 7.0.6-6 allows remote attackers to cause a denial of service (memory consumption) via a crafted BMP file.

This update for ImageMagick fixes several issues.

These security issues were fixed:

• CVE-2018-8804: The WriteEPTImage function allowed remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact via a crafted file (bsc#1086011).
• 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-2017-18209: Prevent NULL pointer dereference in the GetOpenCLCachedFilesDirectory function caused by a memory allocation result that was not checked, related to GetOpenCLCacheDirectory (bsc#1083628).
• CVE-2017-18211: Prevent NULL pointer dereference in the function saveBinaryCLProgram caused by a program-lookup result not being checked, related to CacheOpenCLKernel (bsc#1083634).
• CVE-2017-9500: Prevent assertion failure in the function ResetImageProfileIterator, which allowed attackers to cause a denial of service via a crafted file (bsc#1043290).
• CVE-2017-14739: The AcquireResampleFilterThreadSet function mishandled failed memory allocation, which allowed remote attackers to cause a denial of service (NULL Pointer Dereference in DistortImage in MagickCore/distort.c, and application crash) via unspecified vectors (bsc#1060382).
• 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-2017-13768: Prevent NULL pointer dereference in the IdentifyImage function that allowed an attacker to perform denial of service by sending a crafted image file (bsc#1056434).
• 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-2018-7470: The IsWEBPImageLossless function allowed attackers to cause a denial of service (segmentation violation) via a crafted file (bsc#1082837).
• CVE-2018-7443: The ReadTIFFImage function did not properly validate the amount of image data in a file, which allowed remote attackers to cause a denial of service (memory allocation failure in the AcquireMagickMemory function in MagickCore/memory.c) (bsc#1082792).
• 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-2017-12692: The ReadVIFFImage function allowed remote attackers to cause a denial of service (memory consumption) via a crafted VIFF file (bsc#1082362).
• CVE-2017-12693: The ReadBMPImage function allowed remote attackers to cause a denial of service (memory consumption) via a crafted BMP file (bsc#1082348).

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.
