Ghost Vulnerability. Glibc buffer overflow. Maybe another hartbleeding. Go fix your system now.

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.

Pretty sure this about the third thread on this vulnerability.

Yeah it's too late to patch.
Misleading title. I thought there was another glibc vulnerability, a Ghost vulnerability (in the blog software) and maybe another OpenSSL one.
