CVE-2020-27750

https://notcve.org/view.php?id=CVE-2020-27750

08 Dec 2020 — A flaw was found in ImageMagick in MagickCore/colorspace-private.h and MagickCore/quantum.h. 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 char` and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. Se encontró un fallo ... • https://bugzilla.redhat.com/show_bug.cgi?id=1891984 • CWE-369: Divide By Zero •

CVE-2020-25674 – Ubuntu Security Notice USN-5335-1

https://notcve.org/view.php?id=CVE-2020-25674

08 Dec 2020 — WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. The patch replaces the hardcoded 256 value with a call to MagickMin() to ensure the proper value is used. This could impact application availability when a ... • https://bugzilla.redhat.com/show_bug.cgi?id=1891928 • CWE-122: Heap-based Buffer Overflow •

08 Dec 2020 — A flaw was found in ImageMagick in coders/txt.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`. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.8-68.

08 Dec 2020 — 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. The flaw could be triggered by a crafted input file under certain conditions when it is processed by ImageMagick. Red Hat Product Security marked this as Low because although it could potentially lead to an impact to application availability, no specific impact was shown in this case.

CVE-2020-25665

https://notcve.org/view.php?id=CVE-2020-25665

08 Dec 2020 — The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause impact to reliability.

04 Dec 2020 — Due to a missing check for 0 value of `replace_extent`, it is possible for offset `p` to overflow in SubstituteString(), causing potential impact to application availability. This could be triggered by a crafted input file that is processed by ImageMagick. This flaw affects ImageMagick versions prior to 7.0.8-68.

04 Dec 2020 — 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. The patch casts the return value of GetPixelIndex() to ssize_t type to avoid this bug. This undefined behavior could be triggered when ImageMagick processes a crafted pdf file. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impa... • https://bugzilla.redhat.com/show_bug.cgi?id=1898290 • CWE-190: Integer Overflow or Wraparound •
