Fedora Update Notification
2014-08-28 14:38:55

Name        : glibc
Product     : Fedora 20
Version     : 2.18
Release     : 14.fc20
URL         : http://www.gnu.org/software/glibc/
Summary     : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

Update Information:

* 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)
