    "description": "Summary:\nA resource leak was identified in src/tool_parsecfg.c using the Clang Static Analyzer. When a file error occurs (fileerror is true) during config parsing, the function returns PARAM_READ_ERROR without ensuring the file stream is properly closed, leading to a potential file descriptor leak.\n\nSteps to Reproduce:\n\n    1. Analyze the curl source code using scan-build make.\n\n    2. Observe the report for src/tool_parsecfg.c.\n\n    3. The analyzer identifies that at line 264, if fileerror is triggered, the                   control flow reaches the return statement at line 279 without\n a confirmed fclose on the opened stream.\n\n## Impact\n\nImpact:\nA local attacker could potentially cause a Denial of Service (DoS) by repeatedly triggering this error path, leading to file descriptor exhaustion.",
