"The Qualys Research Labs discovered various problems in the dynamic
linker of the GNU C Library which allow local privilege escalation by
clashing the stack. For the full details, please refer to their
advisory published at:
https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt

For Debian 7 'Wheezy', these problems have been fixed in version
2.13-38+deb7u12.

We recommend that you 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."
