            Bug ID: 21594
           Summary: global-buffer-overflow in OP_G
           Product: binutils
           Version: 2.29 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: aadamski at quarkslab dot com
  Target Milestone: ---

Hello there,

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 used was `objdump -D <file>`. The compilation flags used were `-g
-O2 -fno-omit-frame-pointer -fsanitize=address
-fno-sanitize-recover=undefined`. The configuration settings used were
`--enable-targets=all --disable-shared`.

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