The d_print_comp function in cp-demangle.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, which triggers infinite recursion and a buffer overflow, related to a node having "itself as ancestor more than once."

The remote Redhat Enterprise Linux 5 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.

  - gcc: integer overflow flaws in libgfortran (CVE-2014-5044)

  - Integer overflow in the new[] operator in gcc before 4.8.0 allows attackers to have unspecified impacts.
    (CVE-2002-2439)

  - Integer overflow in the string_appends function in cplus-dem.c in libiberty allows remote attackers to     execute arbitrary code via a crafted executable, which triggers a buffer overflow. (CVE-2016-2226)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 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.

  - gcc: integer overflow flaws in libgfortran (CVE-2014-5044)

  - The std::random_device class in libstdc++ in the GNU Compiler Collection (aka GCC) before 4.9.4 does not     properly handle short reads from blocking sources, which makes it easier for context-dependent attackers     to predict the random values via unspecified vectors. (CVE-2015-5276)
