"A possible invalid free was introduced in libx11 2:1.5.0-1+deb7u3,
which could lead to application crashes or other issues.

For Debian 7 'Wheezy', these problems have been fixed in version
2:1.5.0-1+deb7u4.

We recommend that you upgrade your libx11 packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
