Denial of Service via crafted image due to missing memory allocation check
Summary
ImageMagick before 7.1.2-26 and 6.9.13-51 is missing a check for the allowed memory allocation limit in matrix-backed operations such as -canny. An attacker can supply a crafted image that causes ImageMagick to allocate more memory than permitted by the configured policy, resulting in a denial of service. A flaw was found in ImageMagick. A remote attacker could provide a specially crafted image, causing the software to allocate more memory than permitted by its configuration. This can lead to a denial of service (DoS), making the system or application unavailable to legitimate users. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-770. Under investigation: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7.
- < 7.1.2-26
- < 6.9.13-51
