Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileDownlink SendPartial range validation is vulnerable because the wrapping sum bypasses file-range validation, becomes m_endOffset, and leaves m_byteOffset greater than the wrapped end offset. When an existing source file is larger than the supplied startOffset and a caller able to issue SendPartial supplies a length whose U32 sum with that offset wraps, the first data-packet send reaches FW_ASSERT and aborts or resets the process, causing denial of service. This issue is fixed in version 4.3.0.
