An issue was discovered in ImageMagick 7.0.7-22 Q16. The IsWEBPImageLossless function in coders/webp.c allows attackers to cause a denial of service (segmentation violation) via a crafted file.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in ImageMagick 7.0.7-22 Q16. The IsWEBPImageLossless function in coders/webp.c     allows attackers to cause a denial of service (segmentation violation) via a crafted file. (CVE-2018-7470)

Note that Nessus relies on the presence of the package as reported by the vendor.

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). This     update was imported from the SUSE:SLE-12:Update update     project.
