DescriptionCVE.org

ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in color transformation to the log colorspace: when the operation fails, a small amount of memory is not released.

AnalysisAI

ImageMagick's log colorspace color transformation leaks a small amount of memory when the operation fails, affecting versions prior to 7.1.2-26 and 6.9.13-51. The flaw (CWE-401) resides in an error-handling code path that fails to release allocated memory, meaning repeated invocations that trigger failures could contribute to incremental memory exhaustion. …

Vulnerability AssessmentAI

Exploitation Exploitation requires local execution of ImageMagick (AV:L) and the ability to trigger a failure within the log colorspace color transformation code path (AC:H, AT:P). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:L/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N) assigns a score of 2.1, reflecting the narrow conditions required to trigger the leak and its limited impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local process or unprivileged user repeatedly invokes ImageMagick with a log colorspace transformation that is engineered or happens to fail (e.g., through a malformed or unsupported input image), causing the application to accumulate small memory leaks with each failed call. Over a large number of iterations, this could contribute marginally to memory pressure on the host, though the practical availability impact is minimal given the 'small amount of memory' described per occurrence. …
Remediation Upgrade to ImageMagick 7.1.2-26 or later for the current stable branch, or to 6.9.13-51 or later for the legacy 6.x branch. … Detailed patch versions, workarounds, and compensating controls in full report.
