Doc Text:
An invalid free flaw was found in glibc's getaddrinfo() function when used with the AI_IDN flag. A remote attacker able to make an application call this function could use this flaw to execute arbitrary code with the permissions of the user running the application. Note that this flaw only affected applications using glibc compiled with libidn support.

Description Huzaifa S. Sidhpurwala 2015-01-28 01:50:44 EST 
An Invalid-free() flaw was found in the getaddrinfo() syscall of glibc. The bug only materializes if the getaddrinfo functions is called with
the AI_IDN flag, and if glibc has been compiled with libidn support. 

This flaw was fixed in glibc-2.15 via the following commit:
