Vulnerabilidades

In GraphicsMagick 1.4 snapshot-20181209 Q8 on 32-bit platforms, there is a heap-based buffer over-read in the ReadBMPImage function of bmp.c, which allows attackers to cause a denial of service via a crafted bmp image file. This only affects GraphicsMagick installations with customized BMP limits.

In GraphicsMagick 1.4 snapshot-20181209 Q8, there is a heap-based buffer overflow in the WriteTGAImage function of tga.c, which allows attackers to cause a denial of service via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.

There is a memory leak in the function WriteMSLImage of coders/msl.c in ImageMagick 7.0.8-13 Q16, and the function ProcessMSLScript of coders/msl.c in GraphicsMagick before 1.3.31.

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.

An issue was discovered in GraphicsMagick 1.3.26. 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.

An issue was discovered in GraphicsMagick 1.3.26. 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.

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.

The ReadOneJNGImage and ReadJNGImage functions in coders/png.c in GraphicsMagick 1.3.26 allow remote attackers to cause a denial of service (magick/blob.c CloseBlob use-after-free) or possibly have unspecified other impact via a crafted file, a related issue to CVE-2017-11403.

An issue was discovered in GraphicsMagick 1.3.26. 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.

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.

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.

LibTIFF before 4.0.6 mishandles the reading of TIFF files, as demonstrated by a heap-based buffer over-read in the ReadTIFFImage function in coders/tiff.c in GraphicsMagick 1.3.27.

In GraphicsMagick 1.4 snapshot-20171217 Q8, there is a heap-based buffer over-read in ReadMNGImage in coders/png.c, related to accessing one byte before testing whether a limit has been reached.

In GraphicsMagick 1.4 snapshot-20171217 Q8, there is a stack-based buffer over-read in WriteWEBPImage in coders/webp.c, related to an incompatibility with libwebp versions, 0.5.0 and later, that use a different structure type.

In GraphicsMagick 1.4 snapshot-20171217 Q8, there is a heap-based buffer over-read in ReadNewsProfile in coders/tiff.c, in which LocaleNCompare reads heap data beyond the allocated region.

In GraphicsMagick 1.3.27a, there is a buffer over-read in ReadPALMImage in coders/palm.c when QuantumDepth is 8.

In GraphicsMagick 1.3.27a, there is a heap-based buffer over-read in ReadOneJNGImage in coders/png.c, related to oFFs chunk allocation.

ReadGRAYImage in coders/gray.c in GraphicsMagick 1.3.26 has a magick/import.c ImportGrayQuantumType heap-based buffer over-read via a crafted file.

ReadCMYKImage in coders/cmyk.c in GraphicsMagick 1.3.26 has a magick/import.c ImportCMYKQuantumType heap-based buffer over-read via a crafted file.

WriteOnePNGImage in coders/png.c in GraphicsMagick 1.3.26 has a heap-based buffer over-read via a crafted file.

ReadRGBImage in coders/rgb.c in GraphicsMagick 1.3.26 has a magick/import.c ImportRGBQuantumType heap-based buffer over-read via a crafted file.

WritePNMImage in coders/pnm.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (bit_stream.c MagickBitStreamMSBWrite heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.

coders/wpg.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to the AcquireCacheNexus function in magick/pixel_cache.c.

The DrawImage function in magick/render.c in GraphicsMagick 1.3.26 does not properly look for pop keywords that are associated with push keywords, which allows remote attackers to cause a denial of service (negative strncpy and application crash) or possibly have unspecified other impact via a crafted file.

The ReadWPGImage function in coders/wpg.c in GraphicsMagick 1.3.26 does not properly validate colormapped images, which allows remote attackers to cause a denial of service (ImportIndexQuantumType invalid write and application crash) or possibly have unspecified other impact via a malformed WPG image.
