Summary
imagemagick vulnerabilities
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 causing a denial of service. (CVE-2021-20246)
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)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
