Title:
  Multiple memory corruption in ld-new (binuitils-2.30-15ubuntu1)

Status in binutils package in Ubuntu:
  Fix Released
Status in binutils source package in Bionic:
  Fix Committed

Bug description:
  Dear all,
  The following binutils ld-new memory corruptions were found by a modified version of the kAFL fuzzer (https://github.com/RUB-SysSec/kAFL). I have attached the crashing inputs and each ASAN report.

  Steps to reproduce:

  Build current verison of binutils:
  ```
  pull-lp-source binutils
  cd binutils-2.30
  CC=clang CXX=clang++ CFLAGS="-fsanitize=address -fsanitize-recover=address -ggdb" CXXFLAGS="-fsanitize=address -fsanitize-recover=address -ggdb" LDFLAGS="-fsanitize=address" ./configure
  CC=clang CXX=clang++ CFLAGS="-fsanitize=address -fsanitize-recover=address -ggdb" CXXFLAGS="-fsanitize=address
  -fsanitize-recover=address -ggdb" LDFLAGS="-fsanitize=address" make
  ```

  Run inputs under ASAN:

  ```
  ASAN_OPTIONS=halt_on_error=false:allow_addr2line=true ./ld-new $file
  ```

  We can verify those issues for ld-new binuitils-2.30-15ubuntu1 (Ubuntu
  16.04.4 LTS / sources from "pull-lp-source bintuils").
