Imagemagick » Imagemagick : Security Vulnerabilities, CVEs, CVSS score between 6 and 6.99

A heap use-after-free flaw was found in coders/bmp.c in ImageMagick.

A heap-based buffer overflow vulnerability was found in coders/tiff.c in ImageMagick. This issue may allow a local attacker to trick the user into opening a specially crafted file, resulting in an application crash and denial of service.

ImageMagick 7.1.0-49 is vulnerable to Information Disclosure. When it parses a PNG image (e.g., for resize), the resulting image could have embedded the content of an arbitrary. file (if the magick binary has permissions to read it).

ImageMagick 7.1.0-49 is vulnerable to Denial of Service. When it parses a PNG image (e.g., for resize), the convert process could be left waiting for stdin input.

A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.

In WriteOnePNGImage() of the PNG coder at coders/png.c, an improper call to AcquireVirtualMemory() and memset() allows for an out-of-bounds write later when PopShortPixel() from MagickCore/quantum-private.h is called. The patch fixes the calls by adding 256 to rowbytes. An attacker who is able to supply a specially crafted image could affect availability with a low impact to data integrity. This flaw affects ImageMagick versions prior to 6.9.10-68 and 7.0.8-68.

ImageMagick before 7.0.9-0 allows remote attackers to cause a denial of service because XML_PARSE_HUGE is not properly restricted in coders/svg.c, related to SVG and libxml2.

ImageMagick 7.0.8-43 has a memory leak in coders/dot.c, as demonstrated by PingImage in MagickCore/constitute.c.

ImageMagick 7.0.8-43 has a memory leak in Huffman2DEncodeImage in coders/ps3.c, as demonstrated by WritePS3Image.

ImageMagick 7.0.8-40 has a memory leak in Huffman2DEncodeImage in coders/ps2.c.

ImageMagick 7.0.8-35 has a memory leak in coders/dot.c, as demonstrated by AcquireMagickMemory in MagickCore/memory.c.

ImageMagick 7.0.8-35 has a memory leak in coders/dps.c, as demonstrated by XCreateImage.

ImageMagick 7.0.8-35 has a memory leak in magick/xwindow.c, related to XCreateImage.

WriteTIFFImage in coders/tiff.c in ImageMagick 7.0.8-43 Q16 allows attackers to cause a denial-of-service (application crash resulting from a heap-based buffer over-read) via a crafted TIFF image file, related to TIFFRewriteDirectory, TIFFWriteDirectory, TIFFWriteDirectorySec, and TIFFWriteDirectoryTagColormap in tif_dirwrite.c of LibTIFF. NOTE: this occurs because of an incomplete fix for CVE-2019-11597.

The XWD image (X Window System window dumping file) parsing component in ImageMagick 7.0.8-41 Q16 allows attackers to cause a denial-of-service (application crash resulting from an out-of-bounds Read) in ReadXWDImage in coders/xwd.c by crafting a corrupted XWD image file, a different vulnerability than CVE-2019-11472.

In ImageMagick 7.x before 7.0.8-41 and 6.x before 6.9.10-41, there is a divide-by-zero vulnerability in the MeanShiftImage function. It allows an attacker to cause a denial of service by sending a crafted file.

In ImageMagick 7.x before 7.0.8-42 and 6.x before 6.9.10-42, there is a use after free vulnerability in the UnmapBlob function that allows an attacker to cause a denial of service by sending a crafted file.

ImageMagick 7.0.8-54 Q16 allows Division by Zero in RemoveDuplicateLayers in MagickCore/layer.c.

ImageMagick 7.0.8-50 Q16 has memory leaks at AcquireMagickMemory because of a wand/mogrify.c error.

ImageMagick 7.0.8-50 Q16 has memory leaks at AcquireMagickMemory because of an error in MagickWand/mogrify.c.

ImageMagick 7.0.8-50 Q16 has memory leaks at AcquireMagickMemory because of mishandling the NoSuchImage error in CLIListOperatorImages in MagickWand/operation.c.

ImageMagick 7.0.8-50 Q16 has memory leaks in AcquireMagickMemory because of an AnnotateImage error.

ImageMagick 7.0.8-50 Q16 has direct memory leaks in AcquireMagickMemory because of an error in CLIListOperatorImages in MagickWand/operation.c for a NULL value.

ImageMagick before 7.0.8-50 has a memory leak vulnerability in the function ReadPSImage in coders/ps.c.

ReadXWDImage in coders/xwd.c in the XWD image parsing component of ImageMagick 7.0.8-41 Q16 allows attackers to cause a denial-of-service (divide-by-zero error) by crafting an XWD image file in which the header indicates neither LSB first nor MSB first.
