ImageMagick before 7.1.2-30 Denial of Service Memory Budget

Assigner: VulnCheck
Reserved: 07.09.2026 Published: 07.09.2026 Updated: 07.09.2026

ImageMagick before 7.1.2-30 and 6.9.13-55 fails to properly lower the memory budget when an operation inside OpenPixelCache fails. Repeated triggering of such failures can exhaust the process memory budget and result in a denial of service.
