  "title": "PNM file-limit bypass causing memory exhaustion in Imager",
  "summary": "Imager versions before 1.041 can undercount memory required when reading certain PNM images, allowing allocations beyond the configured image file limit. An unauthenticated attacker who can submit image data to a service using Imager may cause excessive memory consumption and deny service; explicit format selection is not required when PNM content is auto-detected.",
  "mitigation": "Upgrade Imager to version 1.041 or later. Until upgraded, restrict or isolate processing of untrusted image inputs to reduce exposure.",
