"Arjun Shankar of Red Hat discovered that gethostbyname_r and related
functions compute the size of an input buffer incorrectly if the
passed-in buffer is misaligned. This results in a buffer overflow.

For the oldoldstable distribution (squeeze), this problem has been
fixed in version 2.11.3-4+deb6u6.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
