Impact
A crafted call to the GetVirtualPixels API performs an integer calculation that results in a heap buffer over-write, causing the ImageMagick server process to crash. The flaw is triggered by local input and leads to loss of when the service is overwhelmed with such inputs. The underlying weakness involves an integer overflow (CWE-190) that leads to a heap buffer over-write (CWE-787).
Affected Systems
The vulnerability affects the ImageMagick software suite prior to version 6.9.13-56 and 7.1.2-31. All deployments of ImageMagick below those releases are susceptible.
Risk and Exploitability
With a CVSS score of 5.1, the severity is moderate. No EPSS score is available and the vulnerability is not listed in CISA KEV, suggesting a lower current exploitation footprint. The attack vector is inferred to be local, requiring an attacker to engage the affected API from within the host or through a potentially compromised service that uses ImageMagick to process images.
