Miggo AIRoot Cause Analysis

The vulnerability stems from unsynchronized writes to a shared terminal buffer. Based on:

  1. The description of overlapping writes corrupting packet length fields
  2. The CWE-362 classification indicating improper synchronization
  3. Java package naming conventions for terminal emulation components

While exact patch details are unavailable, terminal data writing methods (writeBlock) and protocol serialization (writeTo) are prime candidates as they would directly handle the vulnerable buffer operations. Confidence is medium due to reliance on vulnerability description patterns rather than explicit patch diffs.
