Gentoo Linux Security Advisory 202405-2 - Multiple vulnerabilities have been discovered in ImageMagick, the worst of which can lead to remote code execution. Versions greater than or equal to 6.9.13.0 are affected.
Ubuntu Security Notice 6200-1 - It was discovered that ImageMagick incorrectly handled the "-authenticate" option for password-protected PDF files. An attacker could possibly use this issue to inject additional shell commands and perform arbitrary code execution. This issue only affected Ubuntu 20.04 LTS. It was discovered that ImageMagick incorrectly handled certain values when processing PDF files. If a user or automated system using ImageMagick were tricked into opening a specially crafted PDF file, an attacker could exploit this to cause a denial of service. This issue only affected Ubuntu 20.04 LTS.
A vulnerability was found in ImageMagick-7.0.11-5, where executing a crafted file with the convert command, ASAN detects memory leaks.
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.
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.
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.
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.

ImageMagick 7.1.0-27 is vulnerable to Buffer Overflow.
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}" />.
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.
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.
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.
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.
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.
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.
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.
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.
