"  - Locale names, including those obtained from environment
    variables (LANG and the LC_* variables), are more
    tightly checked for proper syntax. setlocale will now
    fail (with EINVAL) for locale names that are overly
    long, contain slashes without starting with a slash, or
    contain '..' path components. (CVE-2014-0475)
    Previously, some valid locale names were silently
    replaced with the 'C' locale when running in AT_SECURE
    mode (e.g., in a SUID program). This is no longer
    necessary because of the additional checks.

  - Support for loadable gconv transliteration modules has
    been removed because it did not work at all. Regular
    gconv conversion modules are still supported.
    (CVE-2014-5119)

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
