This commit should fix a heap-use-after-free bug that was caught by the sanitizer bot. The issue is that we were reading memory from a second target into a `SBData` object in Python, that was passed to lldb's internal `ScriptedProcess::DoReadMemory` C++ method. The ScriptedPythonInterface then extracts the underlying `DataExtractor` from the `SBData` object, and is used to read the memory with the appropriate address size and byte order. Unfortunately, it seems that even though the DataExtractor object was still valid, it pointed to invalid, possibly garbage-collected memory from Python. To mitigate this, the patch uses `SBData::SetDataWithOwnership` to copy the pointed buffer to lldb's heap memory which prevents the use-after-free error. rdar://84511405 Differential Revision: https://reviews.llvm.org/D115654 Signed-off-by: Med Ismail Bennani <medismail.bennani@gmail.com> |
