FreeRDP 3.0.0 before 3.32.0 contains a heap out-of-bounds read in freerdp_assistance_parse_all_elements_of() because it advances its parsing cursor without reducing the remaining length, letting the scan window exceed the decrypted ConnectionString2 buffer. Attackers can supply a crafted .msrcIncident invitation file and password that crash xfreerdp when opened, before any RDP connection.
