Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug

Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug information. A logic error in the handling of DWARF compilation units can result in an invalid offset_size value being used inside byte_get_little_endian, leading to an abort (SIGABRT). The issue was observed in binutils 2.44.

A local attacker can trigger the crash by supplying a malicious input file.
