Doc Type: Bug Fix
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.

the AI_IDN flag, and if glibc has been compiled with libidn support.
