Various security issues were discovered in Graphicsmagick, a collection of image processing tools.

CVE-2017-18219 An allocation failure vulnerability was found in the function ReadOnePNGImage in coders/png.c, which allows attackers to cause a denial of service via a crafted file that triggers an attempt at a large png_pixels array allocation.

CVE-2017-18220 The ReadOneJNGImage and ReadJNGImage functions in coders/png.c allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted file, a related issue to CVE-2017-11403.

CVE-2017-18229 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.

CVE-2017-18230 A NULL pointer dereference vulnerability was found in the function ReadCINEONImage in coders/cineon.c, which allows attackers to cause a denial of service via a crafted file.

CVE-2017-18231 A NULL pointer dereference vulnerability was found in the function ReadEnhMetaFile in coders/emf.c, which allows attackers to cause a denial of service via a crafted file.

CVE-2018-9018 There is a divide-by-zero error 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.

For Debian 7 'Wheezy', these problems have been fixed in version 1.3.16-1.1+deb7u19.

We recommend that you upgrade your graphicsmagick packages.

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.

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]

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.
