Description
Driftregion iso14229 before 0.10.1 contains an integer wraparound in Handle_0x38_RequestFileTransfer that lets unauthenticated attackers bypass the file path length check. Attackers can send a short RequestFileTransfer (SID 0x38) request with filePathAndNameLength 0xFFFC-0xFFFF, causing callbacks to read past the receive buffer, crashing targets or disclosing memory.
