"Several vulnerabilities have been fixed in the Debian GNU C Library,
eglibc :

CVE-2016-1234

Alexander Cherepanov discovered that the glibc's glob implementation
suffered from a stack-based buffer overflow when it was called with
the GLOB_ALTDIRFUNC flag and encountered a long file name.

CVE-2016-3075

The getnetbyname implementation in nss_dns was susceptible to a stack
overflow and a crash if it was invoked on a very long name.

CVE-2016-3706

Michael Petlan reported that getaddrinfo copied large amounts of
address data to the stack, possibly leading to a stack overflow. This
complements the fix for CVE-2013-4458.

For Debian 7 'Wheezy', these problems have been fixed in version
2.13-38+deb7u11.

We recommend you to upgrade your eglibc packages.

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."
