PERTAIN_TOReport

binutils/ld: unsafe strcpy/strcat when appending .exe suffix

PERTAIN_TOProblem

strcpy(dst_name, output_filename) followed by strcat(dst_name, ".exe") — when the --force-exe-suffix option is enabled. Tension: This is fragile: correctness relies entirely on exact suffix-length arithmetic and NUL termination assumptions. Outcome: the code allocates dst_name with len+5 bytes.

PERTAIN_TOSolution

Use snprintf(dst_name, len+5, "%s.exe", output_filename). Tension: Avoid strcpy/strcat entirely for composed strings. Outcome: validate remaining space explicitly.
