Heap-based buffer overflow in the DecodeImage function in coders/pict.c in GraphicsMagick before 1.1.14, and 1.2.x before 1.2.3, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted PICT image. NOTE: some of these details are obtained from third party information.

All existing releases of GraphicsMagick and ImageMagick support a file open syntax where if the first character of the file specification is a '|', then the remainder of the filename is passed to the shell for execution using the POSIX popen(3C) function. File opening is handled by an OpenBlob() function in the source file blob.c. Unlike the vulnerability described by CVE-2016-3714, this functionality is supported by the core file opening function rather than a delegates subsystem usually used to execute external programs.

Buffer overflow in the MVG and SVG rendering code in GraphicsMagick 1.3.24 allows remote attackers to have unspecified impact via unknown vectors. Note: This vulnerability exists due to an incomplete patch for CVE-2016-2317.

Heap-based buffer overflow in the EscapeParenthesis function in GraphicsMagick before 1.3.25 allows remote attackers to have unspecified impact via unknown vectors.

Heap-based buffer overflow in the WPG format reader in GraphicsMagick 1.3.25 and earlier allows remote attackers to have unspecified impact via a colormap with a large number of entries.

In GraphicsMagick 1.4 snapshot-20190322 Q8, there is a stack-based buffer overflow in the function SVGStartElement of coders/svg.c, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a quoted font family value.

In GraphicsMagick 1.4 snapshot-20190423 Q8, there is a heap-based buffer overflow in the function ImportRLEPixels of coders/miff.c.

Buffer overflow in GraphicsMagick and ImageMagick allows user-assisted remote attackers to cause a denial of service and possibly execute arbitrary code via a PALM image that is not properly handled by the ReadPALMImage function in coders/palm.c. NOTE: this issue is due to an incomplete patch for CVE-2006-5456.

Multiple heap-based buffer underflows in the ReadPALMImage function in coders/palm.c in GraphicsMagick before 1.2.3 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted PALM image, a different vulnerability than CVE-2007-0770. NOTE: some of these details are obtained from third party information.

GraphicsMagick before 8e56520 has a heap-based buffer over-read in ReadJXLImage in coders/jxl.c, related to an ImportViewPixelArea call.

In GraphicsMagick 1.4 snapshot-20190322 Q8, there is a heap-based buffer over-read in the function ReadMIFFImage of coders/miff.c, which allows attackers to cause a denial of service or information disclosure via an RLE packet.

In GraphicsMagick 1.4 snapshot-20191208 Q8, there is a heap-based buffer over-read in the function EncodeImage of coders/pict.c.

In GraphicsMagick 1.4 snapshot-20190322 Q8, there is a heap-based buffer overflow in the function WriteXWDImage of coders/xwd.c, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image file.

The ReadJNGImage and ReadOneJNGImage functions in coders/png.c in GraphicsMagick 1.3.26 do not properly manage image pointers after certain error conditions, which allows remote attackers to conduct use-after-free attacks via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-11403.
