Local access required to invoke identify; debug mode and non-printable profile terminal byte are specific high-complexity preconditions; only minimal confidentiality impact from one byte.

Lifecycle Timeline
3DescriptionCVE.org
ImageMagick before 7.1.2-26 and 6.9.13-51 contains an information disclosure vulnerability: when a profile is displayed with the identify command and the profile value is not printable, a single byte at the end of the profile can be printed (read past the profile boundary). This behavior occurs when debug output is enabled.
AnalysisAI
ImageMagick before 7.1.2-26 (7.x branch) and 6.9.13-51 (6.x branch) discloses one byte of process memory beyond a profile boundary when the identify command is run with debug output enabled and the embedded profile ends with a non-printable byte. The out-of-bounds read (CWE-125) is highly conditional - requiring local access, explicit debug mode activation, and a specifically crafted profile payload - keeping real-world impact extremely low despite ImageMagick's broad deployment footprint. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three simultaneous non-default conditions: (1) the attacker can cause the `identify` command to process a crafted image containing a metadata profile with a non-printable terminal byte; (2) debug output is explicitly enabled via a debug flag or configuration - this is not the default operational mode; and (3) the attacker has local access or can influence the image input to an `identify` invocation. … 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 accurately characterizes 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 supply a crafted image file to a pipeline running `identify` with debug output enabled submits an image containing a metadata profile whose final byte is non-printable. When ImageMagick processes the file in debug mode, the display routine reads one byte past the profile boundary, potentially printing that byte in the debug output stream. … |
| Remediation | Upgrade to ImageMagick 7.1.2-26 or later for 7.x deployments, or to 6.9.13-51 or later for 6.x deployments, as documented in the vendor advisory at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-hwf3-r46v-5ggx. … Detailed patch versions, workarounds, and compensating controls in full report. |
