Original release date: January 27, 2015

The Linux GNU C Library (glibc) versions prior to 2.18 are vulnerable to remote code execution via a vulnerability in 
the gethostbyname function. Exploitation of this vulnerability may allow a remote attacker to take control of an 
affected system. Linux distributions employing glibc-2.18 and later are not affected.

US-CERT recommends users and administrators refer to their respective Linux or Unix-based OS vendor(s) for an 
appropriate patch if affected. Patches are available from Ubuntu [ http://www.ubuntu.com/usn/usn-2485-1/ ] and Red Hat 
[ https://access.redhat.com/security/cve/CVE-2015-0235 ]. The GNU C Library versions 2.18 and later  [ 
http://www.gnu.org/software/libc/ ]are also available for experienced users and administrators to implement.
