The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ImageMagick 7.0.10-34 allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may     cause a denial of service. (CVE-2020-27560)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4670-1 advisory.

    It was discovered that ImageMagick incorrectly handled certain specially crafted image files. If a user or     automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could     exploit this to cause a denial of service or other unspecified impact. This issue only affected Ubuntu     16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.10. (CVE-2019-19948, CVE-2019-19949)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed.

CVE-2017-14528

The TIFFSetProfiles function in coders/tiff.c has incorrect expectations about whether LibTIFF TIFFGetField return values imply that data validation has occurred, which allows remote attackers to cause a denial of service (use-after-free after an invalid call to TIFFSetField, and application crash) via a crafted file.

CVE-2020-19667

Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c

CVE-2020-25665

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. This could cause impact to reliability.

CVE-2020-25674

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.

CVE-2020-27560

ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service.

CVE-2020-27750

A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould 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.

CVE-2020-27760

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.

CVE-2020-27763

A flaw was found 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.

CVE-2020-27765

A flaw was found 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.

CVE-2020-27773

A flaw was found in MagickCore/gem-private.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` or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior.

CVE-2020-29599

ImageMagick mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.

For Debian 9 stretch, these problems have been fixed in version 8:6.9.7.4+dfsg-11+deb9u11.

We recommend that you upgrade your imagemagick packages.

This update was imported from the SUSE:SLE-15:Update update project.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7068-1 advisory.

    It was discovered that ImageMagick incorrectly handled certain

    malformed image files. If a user or automated system using ImageMagick were tricked into processing a     specially crafted file, an attacker could exploit this to cause a denial of service or affect the     reliability of the system. The vulnerabilities included memory leaks, buffer overflows, and improper     handling of pixel data.
