CVE-2017-11532

When ImageMagick 7.0.6-1 processes a crafted file in convert, it can lead to a Memory Leak in the WriteMPCImage() function in coders/mpc.c.

This update for GraphicsMagick fixes several issues.

These security issues were fixed:

• CVE-2017-14343: Fixed a memory leak vulnerability in ReadXCFImage in coders/xcf.c via a crafted xcf image file (bsc#1058422)
• CVE-2017-12691: The ReadOneLayer function in coders/xcf.c allowed remote attackers to cause a denial of service (memory consumption) via a crafted file (bsc#1058422)
• CVE-2017-14042: Prevent memory allocation failure in the ReadPNMImage function in coders/pnm.c. The vulnerability caused a big memory allocation, which may have lead to remote denial of service in the MagickRealloc function in magick/memory.c (bsc#1056550)
• CVE-2017-13061: A length-validation vulnerability in the function ReadPSDLayersInternal in coders/psd.c allowed attackers to cause a denial of service (ReadPSDImage memory exhaustion) via a crafted file (bsc#1055063)
• CVE-2017-12563: A memory exhaustion vulnerability in the function ReadPSDImage in coders/psd.c allowed attackers to cause a denial of service (bsc#1052460)
• CVE-2017-14174: coders/psd.c allowed for DoS in ReadPSDLayersInternal() due to lack of an EOF (End of File) check might have caused huge CPU consumption. When a crafted PSD file, which claims a large 'length' field in the header but did not contain sufficient backing data, is provided, the loop over 'length' would consume huge CPU resources, since there is no EOF check inside the loop (bsc#1057723)
• CVE-2017-15277: ReadGIFImage in coders/gif.c left the palette uninitialized when processing a GIF file that has neither a global nor local palette. If this functionality was used as a library loaded into a process that operates on interesting data, this data sometimes could have been leaked via the uninitialized palette (bsc#1063050)
• CVE-2017-14733: ReadRLEImage in coders/rle.c mishandled RLE headers that specified too few colors, which allowed remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file (bsc#1060577).
• CVE-2017-12662: Fixed a memory leak vulnerability in WritePDFImage in coders/pdf.c (bsc#1052758).
• CVE-2017-14994: ReadDCMImage in coders/dcm.c allowed remote attackers to cause a denial of service (NULL pointer dereference) via a crafted DICOM image, related to the ability of DCM_ReadNonNativeImages to yield an image list with zero frames (bsc#1061587).
• CVE-2017-12140: The ReadDCMImage function in coders\dcm.c had an integer signedness error leading to excessive memory consumption via a crafted DCM file (bsc#1051847).
• CVE-2017-12644: Fixed memory leak vulnerability in ReadDCMImage in coders\dcm.c (bsc#1052764).
• CVE-2017-11188: The ReadDPXImage function in coders\dpx.c had a large loop vulnerability that can cause CPU exhaustion via a crafted DPX file, related to lack of an EOF check (bsc#1048457).
• CVE-2017-10799: When processing a DPX image (with metadata indicating a large width) in coders/dpx.c, a denial of service (OOM) could have occurred in ReadDPXImage() (bsc#1047054).
• CVE-2017-11449: coders/mpc did not enable seekable streams and thus could not validate blob sizes, which allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an image received from stdin (bsc#1049373).
• CVE-2017-11532: Prevent a memory leak vulnerability in the WriteMPCImage() function in coders/mpc.c via a crafted file allowing for DoS (bsc#1050129).
• CVE-2017-12430: A memory exhaustion in the function ReadMPCImage in coders/mpc.c allowed attackers to cause DoS (bsc#1052252).
• CVE-2017-12642: Prevent a memory leak vulnerability in ReadMPCImage in coders\mpc.c via crafted file allowing for DoS (bsc#1052771).
• CVE-2017-14249: A mishandled EOF check in ReadMPCImage in coders/mpc.c that lead to a division by zero in GetPixelCacheTileSize in MagickCore/cache.c allowed remote attackers to cause a denial of service via a…

This update for ImageMagick fixes the following security issues:

• CVE-2017-11532: Prevent a memory leak vulnerability in the WriteMPCImage() function in coders/mpc.c via a crafted file allowing for DoS (bsc#1050129)
• CVE-2018-16750: Prevent memory leak in the formatIPTCfromBuffer function (bsc#1108283)
• CVE-2018-16749: Added missing NULL check in ReadOneJNGImage that allowed an attacker to cause a denial of service (WriteBlob assertion failure and application exit) via a crafted file (bsc#1108282)
• CVE-2018-16642: The function InsertRow allowed remote attackers to cause a denial of service via a crafted image file due to an out-of-bounds write (bsc#1107616)
• CVE-2018-16640: Prevent memory leak in the function ReadOneJNGImage (bsc#1107619)
• CVE-2018-16643: The functions ReadDCMImage, ReadPWPImage, ReadCALSImage, and ReadPICTImage did check the return value of the fputc function, which allowed remote attackers to cause a denial of service via a crafted image file (bsc#1107612)
• CVE-2018-16644: Added missing check for length in the functions ReadDCMImage and ReadPICTImage, which allowed remote attackers to cause a denial of service via a crafted image (bsc#1107609)
• CVE-2018-16645: Prevent excessive memory allocation issue in the functions ReadBMPImage and ReadDIBImage, which allowed remote attackers to cause a denial of service via a crafted image file (bsc#1107604)
• CVE-2018-16413: Prevent heap-based buffer over-read in the PushShortPixel function leading to DoS (bsc#1106989)

This update also relaxes the restrictions of use of Postscript like formats to 'write' only. (bsc#1105592)

This update for ImageMagick fixes the following issues:

• CVE-2017-14997: ImageMagick allowed remote attackers to cause a denial of service (excessive memory allocation) because of an integer underflow in ReadPICTImage in coders/pict.c. (bsc#1112399)
• CVE-2018-16644: A regression in the security fix for the pict coder was fixed (bsc#1107609)
• CVE-2017-11532: When ImageMagick processed a crafted file in convert, it could lead to a Memory Leak in the WriteMPCImage() function in coders/mpc.c. (bsc#1050129)
• CVE-2017-11639: A regression in the security fix in the cip coder was fixed (bsc#1050635)
