Lifecycle Timeline
2DescriptionCVE.org
ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the magnify operation that allows attackers to read out of bounds memory. An unrecognized magnify:method value triggers an out of bounds read, potentially exposing sensitive information or causing denial of service.
AnalysisAI
Heap-based out-of-bounds read in ImageMagick before 7.1.2-19 is triggered when processing an image carrying an unrecognized magnify:method value, causing the magnify operation to read beyond allocated heap memory. Affected systems running any version prior to 7.1.2-19 can be impacted when a user or automated pipeline processes a specially crafted image file, with outcomes ranging from partial memory disclosure to application crash. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a user or automated process invoke ImageMagick's magnify operation on an attacker-controlled image file containing an unrecognized magnify:method value - this is the specific triggering condition per the CVE description. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L) scores 4.8 Medium, reflecting a local attack vector with required user interaction and only low availability impact on the vulnerable system. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious image file embedding an unrecognized magnify:method value in its metadata or processing directives, then uploads it to a web application or shares it with a user whose workflow invokes ImageMagick (e.g., a CMS thumbnail generator, a document converter, or a command-line convert invocation). When ImageMagick's magnify operation processes the file and encounters the unrecognized method value, it performs a heap out-of-bounds read, potentially leaking adjacent heap contents to the attacker (if output is reflected) or crashing the processing process. … |
| Remediation | The primary fix is upgrading to ImageMagick 7.1.2-19 or later, as confirmed by the upstream security advisory GHSA-8vfj-q2cp-5m5j at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-8vfj-q2cp-5m5j. … Detailed patch versions, workarounds, and compensating controls in full report. |
