Stack-Buffer-Overflow in bfd_get_string

A stack-buffer-overflow vulnerability was discovered in bfd_get_string in bfd/ieee.c. The vulnerability occurs when a maliciously crafted input is passed to the function, which can lead to a buffer overflow. The command used to trigger the vulnerability was `objdump -D <file>`, which was fuzzed with American Fuzzy Lop and AddressSanitizer.

Mitigation:

The vulnerability can be mitigated by ensuring that all inputs are properly validated and sanitized.

I have been fuzzing objdump with American Fuzzy Lop and AddressSanitizer.

Please find attached the minimized file causing the issue ("Input") and the
ASAN report log ("Output"). Below is the reduced stacktrace with links to the
corresponding source lines on a GitHub mirror.

The command I used was `objdump -D <file>`.

Let me know if there is any additional information I can provide.
