Value Overflow

ImageMagick is vulnerable to value overflow. An attacker can enter a craftd input file to PixelPacketIntensity which could return overflowed values...

CVE-2020-27770

Due to a missing check for 0 value of replaceextent, 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...

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 by ImageMagick. This could lead to an impact to application availability. The patch uses the PerceptibleReciprocal to prevent the...

DEBIAN-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. The flaw could be triggered by a crafted input file under certain conditions when processed by ImageMagick. Red Hat...

UBUNTU-CVE-2020-27761

WritePALMImage in /coders/palm.c used sizet 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 by ImageMagick. The patch casts to ssizet instead to avoid this issue. Re...

CVE-2020-25693

A flaw was found in CImg in versions prior to 2.9.3. Integer overflows leading to heap buffer overflows in loadpnm can be triggered by a specially crafted input file processed by CImg, which can lead to an impact to application availability or data integrity...
