libraries (libpthread), standard math libraries (libm), and the Name
Server Caching Daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.

A heap-based buffer overflow was found in glibc's
__nss_hostname_digits_dots() function, which is used by the gethostbyname()
and gethostbyname2() glibc function calls. A remote attacker able to make
an application call either of these functions could use this flaw to
execute arbitrary code with the permissions of the user running the
application. (CVE-2015-0235)

Red Hat would like to thank Qualys for reporting this issue.

All glibc users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.");
