  - binutils: heap-based buffer overflow in finish_stab in stabs.c (CVE-2018-12699)

  - The _bfd_vms_save_sized_string function in vms-misc.c in the Binary File Descriptor (BFD) library (aka
    libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause an out of
    bounds heap read via a crafted vms file. (CVE-2017-12449)

  - The _bfd_xcoff_read_ar_hdr function in bfd/coff-rs6000.c and bfd/coff64-rs6000.c in the Binary File
    Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote
    attackers to cause an out of bounds stack read via a crafted COFF image file. (CVE-2017-12451)

is installed.");
