A flaw was found in ImageMagick in coders/webp.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. The highest threat from this vulnerability is to system availability.

The remote Ubuntu 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5736-2 advisory.

  - An integer overflow issue was discovered in ImageMagick's ExportIndexQuantum() function in     MagickCore/quantum-export.c. Function calls to GetPixelIndex() could result in values outside the range of     representable for the 'unsigned char'. When ImageMagick processes a crafted pdf file, this could lead to     an undefined behaviour or a crash. (CVE-2021-20224)

  - A flaw was found in ImageMagick in coders/jp2.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. The highest threat     from this vulnerability is to system availability. (CVE-2021-20241)

  - 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. The     highest threat from this vulnerability is to system availability. (CVE-2021-20243)

  - A flaw was found in ImageMagick in MagickCore/visual-effects.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.
    The highest threat from this vulnerability is to system availability. (CVE-2021-20244)

  - A flaw was found in ImageMagick in coders/webp.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. The highest threat     from this vulnerability is to system availability. (CVE-2021-20245)

  - A flaw was found in ImageMagick in MagickCore/resample.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. The     highest threat from this vulnerability is to system availability. (CVE-2021-20246)

  - A flaw was found in ImageMagick in versions before 7.0.11 and before 6.9.12, where a division by zero in     WaveImage() of MagickCore/visual-effects.c may trigger undefined behavior via a crafted image file     submitted to an application using ImageMagick. The highest threat from this vulnerability is to system     availability. (CVE-2021-20309)

  - A flaw was found in ImageMagick in versions 7.0.11, where an integer overflow in WriteTHUMBNAILImage of     coders/thumbnail.c may trigger undefined behavior via a crafted image file that is submitted by an     attacker and processed by an application using ImageMagick. The highest threat from this vulnerability is     to system availability. (CVE-2021-20312)

  - A flaw was found in ImageMagick in versions before 7.0.11. A potential cipher leak when the calculate     signatures in TransformSignature is possible. The highest threat from this vulnerability is to data     confidentiality. (CVE-2021-20313)

  - A vulnerability was found in ImageMagick-7.0.11-5, where executing a crafted file with the convert     command, ASAN detects memory leaks. (CVE-2021-3574)

  - ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you     may use, copy, modify, and distribute in both open and proprietary applications. In affected versions and     in certain cases, Postscript files could be read and written when specifically excluded by a `module`     policy in `policy.xml`. ex. <policy domain=module rights=none pattern=PS />. The issue has been     resolved in ImageMagick 7.1.0-7 and in 6.9.12-22. Fortunately, in the wild, few users utilize the `module`     policy and instead use the `coder` policy that is also our workaround recommendation: <policy     domain=coder rights=none pattern={PS,EPI,EPS,EPSF,EPSI} />. (CVE-2021-39212)

  - A flaw was found in ImageMagick. The vulnerability occurs due to improper use of open functions and leads     to a denial of service. This flaw allows an attacker to crash the system. (CVE-2021-4219)

  - A heap-use-after-free flaw was found in ImageMagick's RelinquishDCMInfo() function of dcm.c file. This     vulnerability is triggered when an attacker passes a specially crafted DICOM image file to ImageMagick for     conversion, potentially leading to information disclosure and a denial of service. (CVE-2022-1114)

  - ImageMagick 7.1.0-27 is vulnerable to Buffer Overflow. (CVE-2022-28463)

  - A vulnerability was found in ImageMagick, causing an outside the range of representable values of type     'unsigned char' at coders/psd.c, when crafted or untrusted input is processed. This leads to a negative     impact to application availability or other problems related to undefined behavior. (CVE-2022-32545)

  - A vulnerability was found in ImageMagick, causing an outside the range of representable values of type     'unsigned long' at coders/pcl.c, when crafted or untrusted input is processed. This leads to a negative     impact to application availability or other problems related to undefined behavior. (CVE-2022-32546)

  - In ImageMagick, there is load of misaligned address for type 'double', which requires 8 byte alignment and     for type 'float', which requires 4 byte alignment at MagickCore/property.c. Whenever crafted or untrusted     input is processed by ImageMagick, this causes a negative impact to application availability or other     problems related to undefined behavior. (CVE-2022-32547)

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