In ImageMagick 7.0.7, a NULL pointer dereference vulnerability was found in the function saveBinaryCLProgram in magick/opencl.c because a program-lookup result is not checked, related to CacheOpenCLKernel.

Debian Bug : 870020 870019 876105 869727 886281 873059 870504 870530 870107 872609 875338 875339 875341 873871 873131 875352 878506 875503 875502 876105 876099 878546 878545 877354 877355 878524 878547 878548 878555 878554 878548 878555 878554 878579 885942 886584 928206 941670 931447 932079

Several security vulnerabilities were found in Imagemagick. Various memory handling problems and cases of missing or incomplete input sanitizing may result in denial of service, memory or CPU exhaustion, information disclosure or potentially the execution of arbitrary code when a malformed image file is processed.

For Debian 9 stretch, these problems have been fixed in version 8:6.9.7.4+dfsg-11+deb9u10.

We recommend that you upgrade your imagemagick packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3681-1 advisory.

    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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.
