According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In ImageMagick 7.0.7-29 and earlier, a memory leak in the formatIPTCfromBuffer function in coders/meta.c     was found. (CVE-2018-16750)

  - The ReadTIFFImage function in coders/tiff.c in ImageMagick 7.0.7-26 Q16 does not properly restrict memory     allocation, leading to a heap-based buffer over-read. (CVE-2018-8960)

  - ImageMagick 7.0.7-26 Q16 has excessive iteration in the DecodeLabImage and EncodeLabImage functions     (coders/tiff.c), which results in a hang (tens of minutes) with a tiny PoC file. Remote attackers could     leverage this vulnerability to cause a denial of service via a crafted tiff file. (CVE-2018-9133)

  - The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine     WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the     routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause     impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-25665)

  - There are 4 places in HistogramCompare() in MagickCore/histogram.c where an integer overflow is possible     during simple math calculations. This occurs in the rgb values and `count` value for a color. The patch     uses casts to `ssize_t` type for these calculations, instead of `int`. This flaw could impact application     reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick     versions prior to 7.0.9-0. (CVE-2020-25666)

  - TIFFGetProfiles() in /coders/tiff.c calls strstr() which causes a large out-of-bounds read when it     searches for `'dc:format=\'image/dng\'` within `profile` due to improper string handling, when a crafted     input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to     remedy this. This could cause an impact to availability of the application. This flaw affects ImageMagick     versions prior to 7.0.9-0. (CVE-2020-25667)

  - WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that     can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the     colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass     invalid colormap data to the event logger. The patch replaces the hardcoded 256 value with a call to     MagickMin() to ensure the proper value is used. This could impact application availability when a     specially crafted input file is processed by ImageMagick. This flaw affects ImageMagick versions prior to     7.0.8-68. (CVE-2020-25674)

  - In the CropImage() and CropImageToTiles() routines of MagickCore/transform.c, rounding calculations     performed on unconstrained pixel offsets was causing undefined behavior in the form of integer overflow     and out-of-range values as reported by UndefinedBehaviorSanitizer. Such issues could cause a negative     impact to application availability or other problems related to undefined behavior, in cases where     ImageMagick processes untrusted input data. The upstream patch introduces functionality to constrain the     pixel offsets and prevent these issues. This flaw affects ImageMagick versions prior to 7.0.9-0.
    (CVE-2020-25675)

  - In CatromWeights(), MeshInterpolate(), InterpolatePixelChannel(), InterpolatePixelChannels(), and     InterpolatePixelInfo(), which are all functions in /MagickCore/pixel.c, there were multiple unconstrained     pixel offset calculations which were being used with the floor() function. These calculations produced     undefined behavior in the form of out-of-range and integer overflows, as identified by     UndefinedBehaviorSanitizer. These instances of undefined behavior could be triggered by an attacker who is     able to supply a crafted input file to be processed by ImageMagick. These issues could impact application     availability or potentially cause other problems related to undefined behavior. This flaw affects     ImageMagick versions prior to 7.0.9-0. (CVE-2020-25676)

  - A flaw was found in ImageMagick in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker     who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form     of values outside the range of type `unsigned char` and math division by zero. This would most likely lead     to an impact to application availability, but could potentially cause other problems related to undefined     behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27750)

  - A flaw was found in ImageMagick in MagickCore/quantum-export.c. An attacker who submits a crafted file     that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range     of type `unsigned long long` as well as a shift exponent that is too large for 64-bit type. This would     most likely lead to an impact to application availability, but could potentially cause other problems     related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27751)

  - There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values,     which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact     to application availability or cause a denial of service. It was originally reported that the issues were     in `AcquireMagickMemory()` because that is where LeakSanitizer detected the leaks, but the patch resolves     issues in the MIFF coder, which incorrectly handles data being passed to `AcquireMagickMemory()`. This     flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27753)

  - In IntensityCompare() of /magick/quantize.c, there are calls to PixelPacketIntensity() which could return     overflowed values to the caller when ImageMagick processes a crafted input file. To mitigate this, the     patch introduces and uses the ConstrainPixelIntensity() function, which forces the pixel intensities to be     within the proper bounds in the event of an overflow. This flaw affects ImageMagick versions prior to     6.9.10-69 and 7.0.8-69. (CVE-2020-27754)

  - in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because     the code which checks for the proper image depth size does not reset the size in the event there is an     invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak     can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to     application reliability, such as denial of service. This flaw affects ImageMagick versions prior to     7.0.9-0. (CVE-2020-27755)

  - In ParseMetaGeometry() of MagickCore/geometry.c, image height and width calculations can lead to divide-     by-zero conditions which also lead to undefined behavior.

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - ReadXBMImage in coders/xbm.c in ImageMagick before 7.0.8-9 leaves data uninitialized when processing an     XBM file that has a negative pixel value. If the affected code is used as a library loaded into a process     that includes sensitive information, that information sometimes can be leaked via the image data.
    (CVE-2018-16323)

  - In ImageMagick 7.0.7-29 and earlier, a memory leak in the formatIPTCfromBuffer function in coders/meta.c     was found. (CVE-2018-16750)

  - In coders/bmp.c in ImageMagick before 7.0.8-16, an input file can result in an infinite loop and hang,     with high CPU and memory consumption. Remote attackers could leverage this vulnerability to cause a denial     of service via a crafted file. (CVE-2018-20467)

  - ImageMagick 7.0.7-26 Q16 has excessive iteration in the DecodeLabImage and EncodeLabImage functions     (coders/tiff.c), which results in a hang (tens of minutes) with a tiny PoC file. Remote attackers could     leverage this vulnerability to cause a denial of service via a crafted tiff file. (CVE-2018-9133)

  - 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.
    (CVE-2019-14980)

  - 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.
    (CVE-2019-14981)

  - The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine     WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the     routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause     impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-25665)

  - There are 4 places in HistogramCompare() in MagickCore/histogram.c where an integer overflow is possible     during simple math calculations. This occurs in the rgb values and `count` value for a color. The patch     uses casts to `ssize_t` type for these calculations, instead of `int`. This flaw could impact application     reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick     versions prior to 7.0.9-0. (CVE-2020-25666)

  - TIFFGetProfiles() in /coders/tiff.c calls strstr() which causes a large out-of-bounds read when it     searches for `'dc:format=\'image/dng\'` within `profile` due to improper string handling, when a crafted     input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to     remedy this. This could cause an impact to availability of the application. This flaw affects ImageMagick     versions prior to 7.0.9-0. (CVE-2020-25667)

  - WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that     can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the     colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass     invalid colormap data to the event logger. The patch replaces the hardcoded 256 value with a call to     MagickMin() to ensure the proper value is used. This could impact application availability when a     specially crafted input file is processed by ImageMagick. This flaw affects ImageMagick versions prior to     7.0.8-68. (CVE-2020-25674)

  - In the CropImage() and CropImageToTiles() routines of MagickCore/transform.c, rounding calculations     performed on unconstrained pixel offsets was causing undefined behavior in the form of integer overflow     and out-of-range values as reported by UndefinedBehaviorSanitizer. Such issues could cause a negative     impact to application availability or other problems related to undefined behavior, in cases where     ImageMagick processes untrusted input data. The upstream patch introduces functionality to constrain the     pixel offsets and prevent these issues. This flaw affects ImageMagick versions prior to 7.0.9-0.
    (CVE-2020-25675)

  - In CatromWeights(), MeshInterpolate(), InterpolatePixelChannel(), InterpolatePixelChannels(), and     InterpolatePixelInfo(), which are all functions in /MagickCore/pixel.c, there were multiple unconstrained     pixel offset calculations which were being used with the floor() function. These calculations produced     undefined behavior in the form of out-of-range and integer overflows, as identified by     UndefinedBehaviorSanitizer. These instances of undefined behavior could be triggered by an attacker who is     able to supply a crafted input file to be processed by ImageMagick. These issues could impact application     availability or potentially cause other problems related to undefined behavior. This flaw affects     ImageMagick versions prior to 7.0.9-0.

This would     most likely lead to an impact to application availability, but could potentially cause other problems     related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27751)

  - There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values,     which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact     to application availability or cause a denial of service. It was originally reported that the issues were     in `AcquireMagickMemory()` because that is where LeakSanitizer detected the leaks, but the patch resolves     issues in the MIFF coder, which incorrectly handles data being passed to `AcquireMagickMemory()`. This     flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27753)

  - In IntensityCompare() of /magick/quantize.c, there are calls to PixelPacketIntensity() which could return     overflowed values to the caller when ImageMagick processes a crafted input file. To mitigate this, the     patch introduces and uses the ConstrainPixelIntensity() function, which forces the pixel intensities to be     within the proper bounds in the event of an overflow. This flaw affects ImageMagick versions prior to     6.9.10-69 and 7.0.8-69. (CVE-2020-27754)

  - in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because     the code which checks for the proper image depth size does not reset the size in the event there is an     invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak     can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to     application reliability, such as denial of service. This flaw affects ImageMagick versions prior to     7.0.9-0. (CVE-2020-27755)

  - In ParseMetaGeometry() of MagickCore/geometry.c, image height and width calculations can lead to divide-     by-zero conditions which also lead to undefined behavior. This flaw can be triggered by a crafted input     file processed by ImageMagick and could impact application availability. The patch uses multiplication in     addition to the function `PerceptibleReciprocal()` in order to prevent such divide-by-zero conditions.
    This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27756)

According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine     WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the     routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause     impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-25665)

  - There are 4 places in HistogramCompare() in MagickCore/histogram.c where an integer overflow is possible     during simple math calculations. This occurs in the rgb values and `count` value for a color. The patch     uses casts to `ssize_t` type for these calculations, instead of `int`. This flaw could impact application     reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick     versions prior to 7.0.9-0. (CVE-2020-25666)

  - TIFFGetProfiles() in /coders/tiff.c calls strstr() which causes a large out-of-bounds read when it     searches for `'dc:format=\'image/dng\'` within `profile` due to improper string handling, when a crafted     input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to     remedy this. This could cause an impact to availability of the application. This flaw affects ImageMagick     versions prior to 7.0.9-0. (CVE-2020-25667)

  - WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that     can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the     colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass     invalid colormap data to the event logger. The patch replaces the hardcoded 256 value with a call to     MagickMin() to ensure the proper value is used. This could impact application availability when a     specially crafted input file is processed by ImageMagick. This flaw affects ImageMagick versions prior to     7.0.8-68. (CVE-2020-25674)

  - In the CropImage() and CropImageToTiles() routines of MagickCore/transform.c, rounding calculations     performed on unconstrained pixel offsets was causing undefined behavior in the form of integer overflow     and out-of-range values as reported by UndefinedBehaviorSanitizer. Such issues could cause a negative     impact to application availability or other problems related to undefined behavior, in cases where     ImageMagick processes untrusted input data. The upstream patch introduces functionality to constrain the     pixel offsets and prevent these issues. This flaw affects ImageMagick versions prior to 7.0.9-0.
    (CVE-2020-25675)

  - In CatromWeights(), MeshInterpolate(), InterpolatePixelChannel(), InterpolatePixelChannels(), and     InterpolatePixelInfo(), which are all functions in /MagickCore/pixel.c, there were multiple unconstrained     pixel offset calculations which were being used with the floor() function. These calculations produced     undefined behavior in the form of out-of-range and integer overflows, as identified by     UndefinedBehaviorSanitizer. These instances of undefined behavior could be triggered by an attacker who is     able to supply a crafted input file to be processed by ImageMagick. These issues could impact application     availability or potentially cause other problems related to undefined behavior. This flaw affects     ImageMagick versions prior to 7.0.9-0. (CVE-2020-25676)

  - A flaw was found in ImageMagick in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker     who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form     of values outside the range of type `unsigned char` and math division by zero. This would most likely lead     to an impact to application availability, but could potentially cause other problems related to undefined     behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27750)

  - A flaw was found in ImageMagick in MagickCore/quantum-export.c. An attacker who submits a crafted file     that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range     of type `unsigned long long` as well as a shift exponent that is too large for 64-bit type. This would     most likely lead to an impact to application availability, but could potentially cause other problems     related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27751)

  - There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values,     which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact     to application availability or cause a denial of service. It was originally reported that the issues were     in `AcquireMagickMemory()` because that is where LeakSanitizer detected the leaks, but the patch resolves     issues in the MIFF coder, which incorrectly handles data being passed to `AcquireMagickMemory()`. This     flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27753)

  - In IntensityCompare() of /magick/quantize.c, there are calls to PixelPacketIntensity() which could return     overflowed values to the caller when ImageMagick processes a crafted input file. To mitigate this, the     patch introduces and uses the ConstrainPixelIntensity() function, which forces the pixel intensities to be     within the proper bounds in the event of an overflow. This flaw affects ImageMagick versions prior to     6.9.10-69 and 7.0.8-69. (CVE-2020-27754)

  - in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because     the code which checks for the proper image depth size does not reset the size in the event there is an     invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak     can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to     application reliability, such as denial of service. This flaw affects ImageMagick versions prior to     7.0.9-0. (CVE-2020-27755)

  - In ParseMetaGeometry() of MagickCore/geometry.c, image height and width calculations can lead to divide-     by-zero conditions which also lead to undefined behavior. This flaw can be triggered by a crafted input     file processed by ImageMagick and could impact application availability. The patch uses multiplication in     addition to the function `PerceptibleReciprocal()` in order to prevent such divide-by-zero conditions.
    This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27756)

  - A floating point math calculation in ScaleAnyToQuantum() of /MagickCore/quantum-private.h could lead to     undefined behavior in the form of a value outside the range of type unsigned long long. The flaw could be     triggered by a crafted input file under certain conditions when it is processed by ImageMagick. Red Hat     Product Security marked this as Low because although it could potentially lead to an impact to application     availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to     7.0.8-68. (CVE-2020-27757)

  - A flaw was found in ImageMagick in coders/txt.c. An attacker who submits a crafted file that is processed     by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned     long long`. This would most likely lead to an impact to application availability, but could potentially     cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to     7.0.8-68. (CVE-2020-27758)

  - In IntensityCompare() of /MagickCore/quantize.c, a double value was being casted to int and returned,     which in some cases caused a value outside the range of type `int` to be returned. The flaw could be     triggered by a crafted input file under certain conditions when processed by ImageMagick. Red Hat Product     Security marked this as Low severity because although it could potentially lead to an impact to     application availability, no specific impact was shown in this case. This flaw affects ImageMagick     versions prior to 7.0.8-68. (CVE-2020-27759)

  - In `GammaImage()` of /MagickCore/enhance.c, depending on the `gamma` value, it's possible to trigger a     divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an     impact to application availability. The patch uses the `PerceptibleReciprocal()` to prevent the divide-by-     zero from occurring. This flaw affects ImageMagick versions prior to ImageMagick 7.0.8-68.
    (CVE-2020-27760)

  - WritePALMImage() in /coders/palm.c used size_t casts in several areas of a calculation which could lead to     values outside the range of representable type `unsigned long` undefined behavior when a crafted input     file was processed by ImageMagick. The patch casts to `ssize_t` instead to avoid this issue. Red Hat     Product Security marked the Severity as Low because although it could potentially lead to an impact to     application availability, no specific impact was shown in this case. This flaw affects ImageMagick     versions prior to ImageMagick 7.0.9-0. (CVE-2020-27761)

  - A flaw was found in ImageMagick in coders/hdr.c. An attacker who submits a crafted file that is processed     by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned     char`. This would most likely lead to an impact to application availability, but could potentially cause     other problems related to undefined behavior. This flaw affects ImageMagick versions prior to ImageMagick     7.0.8-68. (CVE-2020-27762)

  - A flaw was found in ImageMagick in MagickCore/resize.c. An attacker who submits a crafted file that is     processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would     most likely lead to an impact to application availability, but could potentially cause other problems     related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27763)

  - In /MagickCore/statistic.c, there are several areas in ApplyEvaluateOperator() where a size_t cast should     have been a ssize_t cast, which causes out-of-range values under some circumstances when a crafted input     file is processed by ImageMagick. Red Hat Product Security marked this as Low severity because although it     could potentially lead to an impact to application availability, no specific impact was shown in this     case. This flaw affects ImageMagick versions prior to 6.9.10-69. (CVE-2020-27764)

  - A flaw was found in ImageMagick in MagickCore/segment.c. An attacker who submits a crafted file that is     processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would     most likely lead to an impact to application availability, but could potentially cause other problems     related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27765)

  - A flaw was found in ImageMagick in MagickCore/quantum.h. An attacker who submits a crafted file that is     processed by ImageMagick could trigger undefined behavior in the form of values outside the range of types     `float` and `unsigned char`. This would most likely lead to an impact to application availability, but     could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick     versions prior to 7.0.9-0. (CVE-2020-27767)

  - In ImageMagick, there is an outside the range of representable values of type 'unsigned int' at     MagickCore/quantum-private.h. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27768)

  - In ImageMagick versions before 7.0.9-0, there are outside the range of representable values of type     'float' at MagickCore/quantize.c. (CVE-2020-27769)

  - Due to a missing check for 0 value of `replace_extent`, it is possible for offset `p` to overflow in     SubstituteString(), causing potential impact to application availability. This could be triggered by a     crafted input file that is processed by ImageMagick. This flaw affects ImageMagick versions prior to     7.0.8-68. (CVE-2020-27770)

  - In RestoreMSCWarning() of /coders/pdf.c there are several areas where calls to GetPixelIndex() could     result in values outside the range of representable for the unsigned char type. The patch casts the return     value of GetPixelIndex() to ssize_t type to avoid this bug. This undefined behavior could be triggered     when ImageMagick processes a crafted pdf file. Red Hat Product Security marked this as Low severity     because although it could potentially lead to an impact to application availability, no specific impact     was demonstrated in this case. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27771)

  - A flaw was found in ImageMagick in coders/bmp.c.
