Details

It was discovered that ImageMagick incorrectly handled certain values
when processing visual effects based image files. By tricking a user into
opening a specially crafted image file, an attacker could crash the
application causing a denial of service. (CVE-2021-20244)

It was discovered that ImageMagick incorrectly handled certain values
when performing resampling operations. By tricking a user into opening
a specially crafted image file, an attacker could crash the application

It was discovered that ImageMagick incorrectly handled certain values
when processing visual effects based image files. By tricking a user into
opening a specially crafted image file, an attacker could crash the
application causing a denial of service (CVE-2021-20309)

It was discovered that ImageMagick incorrectly handled certain values
when processing thumbnail image data. By tricking a user into opening
a specially crafted image file, an attacker could crash the application
causing a denial of service. (CVE-2021-20312)

It was discovered that ImageMagick incorrectly handled memory cleanup
when performing certain cryptographic operations. Under certain conditions
sensitive cryptographic information could be disclosed. (CVE-2021-20313)
