apply_relocations in readelf.c in GNU Binutils 2.32 contains an integer overflow that allows attackers to trigger a write access violation (in byte_put_little_endian function in elfcomm.c) via an ELF file, as demonstrated by readelf.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
