The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libiberty: Memory leak in demangle_template function resulting in a denial of service (CVE-2018-20657)

  - The demangle_template function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31.1,     contains an integer overflow vulnerability (for Create an array for saving the template argument values)     that can trigger a heap-based buffer overflow, as demonstrated by nm. (CVE-2018-20673)

According to the versions of the binutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The demangle_template function in cplus-dem.c in GNU     libiberty, as distributed in GNU Binutils 2.31.1,     contains an integer overflow vulnerability (for 'Create     an array for saving the template argument values') that     can trigger a heap-based buffer overflow, as     demonstrated by nm.(CVE-2018-20673)

  - The demangle_template function in cplus-dem.c in GNU     libiberty, as distributed in GNU Binutils 2.31.1, has a     memory leak via a crafted string, leading to a denial     of service (memory consumption), as demonstrated by     cxxfilt, a related issue to     CVE-2018-12698.(CVE-2018-20657)

  - 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)

  - An issue was discovered in GNU libiberty, as     distributed in GNU Binutils 2.32.
    simple_object_elf_match in simple-object-elf.c does not     check for a zero shstrndx value, leading to an integer     overflow and resultant heap-based buffer     overflow.(CVE-2019-14250)
