CVE-2020-27751

A flaw was found 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.

CVE-2021-20243

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.

CVE-2021-20245

A flaw was found 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.

CVE-2021-20309

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.

CVE-2021-20312

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.

CVE-2021-20313

A potential cipher leak when the calculate signatures in TransformSignature is possible.

For Debian 9 stretch, these problems have been fixed in version 8:6.9.7.4+dfsg-11+deb9u13.

We recommend that you upgrade your imagemagick packages.

For the detailed security status of imagemagick please refer to its security tracker page at: [link moved to references]
