Debian Bug : 1027164 1030767

Several vulnerabilities have been discovered in imagemagick that may
lead to a privilege escalation, denial of service or information leaks.

CVE-2020-19667

A stack-based buffer overflow and unconditional jump was found in
ReadXPMImage in coders/xpm.c

CVE-2020-25665

An out-of-bounds read in the PALM image coder was found in
WritePALMImage in coders/palm.c

CVE-2020-25666

An integer overflow was possible during simple math
calculations in HistogramCompare() in MagickCore/histogram.c

CVE-2020-25674

A for loop with an improper exit condition was found that can
allow an out-of-bounds READ via heap-buffer-overflow in
WriteOnePNGImage from coders/png.c

CVE-2020-25675

A undefined behavior was found in the form of integer overflow
and out-of-range values as a result of rounding calculations
performed on unconstrained pixel offsets in the CropImage()
and CropImageToTiles() routines of MagickCore/transform.c

CVE-2020-25676

A undefined behavior was found in the form of integer overflow
and out-of-range values as a result of rounding calculations
performed on unconstrained pixel offsets in CatromWeights(),
MeshInterpolate(), InterpolatePixelChannel(),
InterpolatePixelChannels(), and InterpolatePixelInfo(),
which are all functions in /MagickCore/pixel.c

CVE-2020-27560

A division by Zero was found in OptimizeLayerFrames in
MagickCore/layer.c, which may cause a denial of service.

CVE-2020-27750

A division by Zero was found in MagickCore/colorspace-private.h
and MagickCore/quantum.h, which may cause a denial of service

CVE-2020-27751

A undefined behavior was found 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 in MagickCore/quantum-export.c

CVE-2020-27754

A integer overflow was found in IntensityCompare() of
/magick/quantize.c

CVE-2020-27756

A division by zero was found in ParseMetaGeometry() of
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.
