MagickCore/geometry.c.
Image height and width calculations can lead to
divide-by-zero conditions which also lead to undefined behavior.
CVE-2020-27757
A undefined behavior was found in MagickCore/quantum-private.h
A floating point math calculation in
ScaleAnyToQuantum() of /MagickCore/quantum-private.h could lead to
undefined behavior in the form of a value outside the range of type
unsigned long long.
CVE-2020-27758
Undefined behavior was found in the form of values outside the
range of type `unsigned long long` in coders/txt.c
CVE-2020-27759
In IntensityCompare() of /MagickCore/quantize.c, a
double value was being casted to int and returned, which in some
cases caused a value outside the range of type `int` to be
returned.
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.
CVE-2020-27761
WritePALMImage() in /coders/palm.c used size_t casts
in several areas of a calculation which could lead to
values outside the range of representable type `unsigned long`
undefined behavior when a crafted input file was processed.
CVE-2020-27762
Undefined behavior was found in the form of values outside the
range of type `unsigned char` in coders/hdr.c
CVE-2020-27763
Undefined behavior was found in the form of math division by
zero in MagickCore/resize.c
CVE-2020-27764
Out-of-range values was found under some
circumstances when a crafted input file is processed in
/MagickCore/statistic.c
CVE-2020-27765
Undefined behavior was found in the form of math division by
zero in MagickCore/segment.c when a crafted file is processed
CVE-2020-27766
A crafted file that is processed by ImageMagick could trigger
undefined behavior in the form of values outside the range of
type `unsigned long`
CVE-2020-27767
Undefined behavior was found in the form of values outside the
range of types `float` and `unsigned char` in MagickCore/quantum.h
CVE-2020-27768
An outside the range of representable values of type
`unsigned int` was found in MagickCore/quantum-private.h
CVE-2020-27769
An outside the range of representable values of type
`float` was found in MagickCore/quantize.c
CVE-2020-27770
Due to a missing check for 0 value of
`replace_extent`, it is possible for offset `p` to overflow in
SubstituteString()
CVE-2020-27771
In RestoreMSCWarning() of /coders/pdf.c there are
several areas where calls to GetPixelIndex() could result in values
outside the range of representable for the `unsigned char` type
CVE-2020-27772
Undefined behavior was found in the form of values outside the
range of type `unsigned int` in coders/bmp.c
CVE-2020-27773
Undefined behavior was found in the form of values outside the
range of type `unsigned char` or division by zero
CVE-2020-27774
A crafted file that is processed by ImageMagick could trigger
undefined behavior in the form of a too large shift for
64-bit type `ssize_t`.
CVE-2020-27775
Undefined behavior was found in the form of values outside the
range of type `unsigned char` in MagickCore/quantum.h
CVE-2020-27776
A crafted file that is processed by ImageMagick could trigger
undefined behavior in the form of values outside the range of
type unsigned long.
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.
On debian system, by default the imagemagick policy
mitigated this CVE.
CVE-2021-3574
A memory leak was found converting a crafted TIFF file.
CVE-2021-3596
A NULL pointer dereference was found in ReadSVGImage() in
coders/svg.c
CVE-2021-20224
An integer overflow issue was discovered in ImageMagick's
ExportIndexQuantum() function in MagickCore/quantum-export.c.
CVE-2022-44267
A Denial of Service was found. When it parses a PNG image,
the convert process could be left waiting for stdin input.
CVE-2022-44268
An Information Disclosure was found. When it parses a PNG image,
(e.g., for resize), the resulting image could have embedded
the content of an arbitrary. file.
For Debian 10 buster, these problems have been fixed in version
8:6.9.10.23+dfsg-2.1+deb10u2.
We recommend that you upgrade your imagemagick packages.
