NVD Description

Note: Versions mentioned in the description apply only to the upstream eglibc package and not the eglibc package as distributed by Ubuntu. See How to fix? for Ubuntu:12.04 relevant fixed versions and status.

The send_dg function in resolv/res_send.c in GNU C Library (aka glibc or libc6) before 2.20 does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.
