PERTAIN_TOReport

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

PERTAIN_TOReport

Potential heap overflow in ld generated-symbol name sizing

PERTAIN_TOReport

Archive symbol table parsing needs strict bound checks before copying member names

PERTAIN_TOSolution

caller-supplied dst. Tension: Avoid strcpy to caller buffers. Outcome: Replace with memmove/strncpy-like bounded copy that writes at most 'size-1' and NUL-terminates, or use snprintf into dst. Ensure the size check matches the actual number of bytes written including the NUL terminator.

PERTAIN_TOProblem

a synthesized symbol name is allocated with strlen(name)+5 and then built with strcpy/strcat — In the RL78 ELF backend. Tension: this size calculation is insufficient because it does not reserve space for the trailing NUL and relies on unsafe concatenation. Outcome: creating a heap overflow path during relocation processing.
