RELATES_TOComponent

PERTAIN_TOSolution

Add check after strtol call: `if (remaining_chunk_size < 0) { return false; }`. Tension: negative not validated before use as read() size. Outcome: wget 1.19.2 added validation of chunk size sign.

PERTAIN_TOProblem

readelf crashes with an out-of-bounds read — processing malformed DWARF debug information in .debug_str_offsets sections. Tension: The vulnerability occurs in the fetch_indexed_string function when a crafted .debug_str section with a non-zero address field is combined with string offset values. Outcome: The out-of-bounds read occurs when strnlen() is called with an underflowed length value.

PERTAIN_TOReport
