Package : imagemagick
Version : 8:6.9.7.4+dfsg-11+deb9u13
CVE ID : CVE-2020-27751 CVE-2021-20243 CVE-2021-20245 CVE-2021-20309
CVE-2021-20312 CVE-2021-20313
Multiple security issues have been discovered in imagemagick.
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.
