  (libm), and the name service cache daemon (nscd) used by multiple programs on
  the system. Without these libraries, the Linux system cannot function correctly.
  Security Fix(es): * A stack overflow vulnerability was found in nan* functions
  that could cause applications, which process long strings with the nan function,
  to crash or, potentially, execute arbitrary code. (CVE-2014-9761) * It was found
  that out-of-range time values passed to the strftime() function could result in
  an out-of-bounds memory access. This could lead to application crash or,
  potentially, information disclosure. (CVE-2015-8776) * An integer overflow
  vulnerability was found in hcreate() and hcreate_r() functions which could
  result in an out-of-bounds memory access. This could lead to application crash
  or, potentially, arbitrary code execution. (CVE-2015-8778) * A stack based
  buffer overflow vulnerability was found in the catopen() function. An
  excessively long string passed to the function could cause it to crash or,
  potentially, execute arbitrary code. (CVE-2015-8779) * It was found that the
  dynamic loader did not sanitize the LD_POINTER_GUARD environment variable. An
  attacker could use this flaw to bypass the pointer guarding protection on
  set-user-ID or set-group-ID programs to execute arbitrary code with the
  permissions of the user running the application. (CVE-2015-8777) Additional
  Changes: For detailed information on changes in this release, see the Red Hat
  Enterprise Linux 7.4 Release Notes linked from the References section.");
