  "title": "Heap buffer overflow in FreeRDP H.264 encoding",
  "summary": "FreeRDP H.264 encoding can write beyond an allocated image buffer after a surface changes height while retaining the same width. An attacker able to cause that resize in an affected encoding path may corrupt heap memory or terminate the FreeRDP process; the issue requires an H.264-encoded surface resize with an unchanged width.",
  "mitigation": "Upgrade FreeRDP to version 3.33.0 or later. Until upgrading, reduce exposure by preventing untrusted clients or content from triggering H.264 surface resizes in affected encoding services.",
