The AcquireCacheNexus function in magick/pixel_cache.c in GraphicsMagick before 1.3.28 allows remote attackers to cause a denial of service (heap overwrite) or possibly have unspecified other impact via a crafted image file, because a pixel staging area is not used.

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

  - The AcquireCacheNexus function in magick/pixel_cache.c in GraphicsMagick before 1.3.28 allows remote     attackers to cause a denial of service (heap overwrite) or possibly have unspecified other impact via a     crafted image file, because a pixel staging area is not used. (CVE-2018-6799)

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

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - In GraphicsMagick 1.3.27, there is an infinite loop and application hang in the ReadBMPImage function
    (coders/bmp.c). Remote attackers could leverage this vulnerability to cause a denial of service via an
    image file with a crafted bit-field mask value. (CVE-2018-5685)

  - The AcquireCacheNexus function in magick/pixel_cache.c in GraphicsMagick before 1.3.28 allows remote
    attackers to cause a denial of service (heap overwrite) or possibly have unspecified other impact via a
    crafted image file, because a pixel staging area is not used. (CVE-2018-6799)

Several vulnerabilities have been discovered in GraphicsMagick, a set of command-line applications to manipulate image files, which could result in denial of service or the execution of arbitrary code if malformed image files are processed.

Various vulnerabilities were discovered in graphicsmagick, a collection of image processing tools and associated libraries, resulting in denial of service, information disclosure, and a variety of buffer overflows and overreads.

For Debian 8 'Jessie', these problems have been fixed in version 1.3.20-3+deb8u4.

We recommend that you upgrade your graphicsmagick packages.

This update for GraphicsMagick fixes the following issues :

  - security update (core)

  - CVE-2018-6799: The AcquireCacheNexus function in     magick/pixel_cache.c in GraphicsMagick before 1.3.28     allows remote attackers to cause a denial of service     (heap overwrite) or possibly have unspecified other     impact via a crafted image file, because a pixel staging     area is not used. [boo#1080522]

  - security update (png.c)

  - CVE-2018-9018: In GraphicsMagick 1.3.28, there is a     divide-by-zero in the ReadMNGImage function of     coders/png.c. Remote attackers could leverage this     vulnerability to cause a crash and denial of service via     a crafted mng file. [boo#1086773]

  - security update (gif.c)

  - CVE-2017-18254: An issue was discovered in ImageMagick     7.0.7. A memory leak vulnerability was found in the     function WriteGIFImage in coders/gif.c, which allow     remote attackers to cause a denial of service via a     crafted file. [boo#1087027]

  - security update (pcd.c)

  - CVE-2017-18251: An issue was discovered in ImageMagick     7.0.7. A memory leak vulnerability was found in the     function ReadPCDImage in coders/pcd.c, which allow     remote attackers to cause a denial of service via a     crafted file. [boo#1087037]

  - CVE-2017-18229: An issue was discovered in     GraphicsMagick 1.3.26. An allocation failure     vulnerability was found in the function ReadTIFFImage in     coders/tiff.c, which allows attackers to cause a denial     of service via a crafted file, because file size is not     properly used to restrict scanline, strip, and tile     allocations. [boo#1085236]

  - CVE-2017-11641: GraphicsMagick 1.3.26 has a Memory Leak     in the PersistCache function in magick/pixel_cache.c     during writing of Magick Persistent Cache (MPC)     files.[boo#1050623]

  - CVE-2017-13066: GraphicsMagick 1.3.26 has a memory leak     vulnerability in the function CloneImage in     magick/image.c. [boo#1055010]

  - CVE-2018-10177: Specially crafted PNG images may have     triggered an infinite loop [bsc#1089781]

A denial of service vulnerability has been discovered in graphicsmagick, a collection of image processing tools and associated libraries.

A specially crafted file can be used to produce a denial of service (heap overwrite) or possible other unspecified impact by exploiting a defect related to unused pixel staging area in the AcquireCacheNexus function in magick/pixel_cache.c.

For Debian 7 'Wheezy', these problems have been fixed in version 1.3.16-1.1+deb7u18.

We recommend that you upgrade your graphicsmagick packages.
