  script_set_attribute(attribute:"description", value:
"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has binutils packages installed that are affected
by multiple vulnerabilities:

  - The bfd_cache_close function in bfd/cache.c in the Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause a heap use after free and
    possibly achieve code execution via a crafted nested archive file. This issue occurs because incorrect
    functions are called during an attempt to release memory. The issue can be addressed by better input
    validation in the bfd_generic_archive_p function in bfd/archive.c. (CVE-2017-12448)

  - remember_Ktype in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30, allows attackers to
    trigger excessive memory consumption (aka OOM). This can occur during execution of cxxfilt.
    (CVE-2018-12934)

  - An issue was discovered in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a
    NULL pointer dereference in work_stuff_copy_to_from when called from iterate_demangle_function.
    (CVE-2018-17794)

  - The get_count function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31, allows remote
    attackers to cause a denial of service (malloc called with the result of an integer-overflowing
    calculation) or possibly have unspecified other impact via a crafted string, as demonstrated by c++filt.
    (CVE-2018-18483)

  - A heap-based buffer over-read issue was discovered in the function sec_merge_hash_lookup in merge.c in the
    Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31, because
    _bfd_add_merge_section mishandles section merges when size is not a multiple of entsize. A specially
    crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld. (CVE-2018-18605)

  - An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU
    Binutils through 2.31. There is a heap-based buffer overflow in bfd_elf32_swap_phdr_in in elfcode.h
    because the number of program headers is not restricted. (CVE-2018-19931)

  - apply_relocations in readelf.c in GNU Binutils 2.32 contains an integer overflow that allows attackers to
    trigger a write access violation (in byte_put_little_endian function in elfcomm.c) via an ELF file, as
    demonstrated by readelf. (CVE-2019-14444)

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