"The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-5341-1 advisory.

  - The dump_relocs_in_section function in objdump.c in GNU Binutils 2.29.1 does not check for reloc count
    integer overflows, which allows remote attackers to cause a denial of service (excessive memory
    allocation, or heap-based buffer overflow and application crash) or possibly have unspecified other impact
    via a crafted PE file. (CVE-2017-17122)

  - There's a flaw in the BFD library of binutils in versions before 2.36. An attacker who supplies a crafted
    file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system
    availability by way of excessive memory consumption. (CVE-2021-3487)

  - stab_xcoff_builtin_type in stabs.c in GNU Binutils through 2.37 allows attackers to cause a denial of
    service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-
    of-bounds write. NOTE: this issue exists because of an incorrect fix for CVE-2018-12699. (CVE-2021-45078)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
