DescriptionCVE.org

ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the TIFF encoder when memory allocation fails. Attackers can trigger allocation failures during TIFF image processing to cause memory exhaustion and denial of service.

AnalysisAI

Memory leak in ImageMagick's TIFF encoder before version 7.1.2-26 enables denial of service via controlled memory allocation failures. An attacker who can submit TIFF images for processing can repeatedly trigger allocation failures, causing the encoder to leak memory without releasing it, ultimately exhausting available system memory. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to have a pathway to submit TIFF images to an ImageMagick-backed processing pipeline running a version before 7.1.2-26. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 2.1 with vector AV:L/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N accurately reflects the constrained real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with the ability to submit TIFF files to a service backed by a vulnerable ImageMagick instance induces repeated TIFF encoding operations under constrained memory conditions, causing each request to leak allocated memory. Sustained submission of such requests gradually exhausts the process's or host's available memory, eventually crashing the image processing service or degrading broader system availability. …
Remediation Upgrade ImageMagick to version 7.1.2-26 or later, which contains the fix for the TIFF encoder memory leak. … Detailed patch versions, workarounds, and compensating controls in full report.
